Video transcript 00:00 hi guys welcome to lead homework today 00:01 we're doing question number four which 00:03 is 00:03 write the greatest four digit number and 00:04 express it in terms of its prime factors 00:07 so first of all let's note down what is 00:08 the greatest four which number so the 00:10 greatest four digit number is nine 00:12 nine nine nine yeah i hope this part is 00:16 clear 00:17 now we have to write the prime 00:18 factorization of that number so let's 00:20 get going 00:20 so i'll be using the blue pen for this 00:22 so let's go ahead and do this so nine 00:25 nine nine and nine right so 00:29 first of all you can divide it by 3 not 00:31 by 2 so dividing by 3 it will give you 3 00:33 3 00:34 3 3 again it can be divided by 3 00:37 so again by 3 so it will give you 1 1 1 00:40 1 this number can be divided by eleven 00:43 by eleven 00:44 it will give you one zero one and then 00:46 one zero one 00:49 this will give you one so this is your 00:51 final answer and when you want to 00:53 express 00:53 nine nine nine nine you can write it as 00:56 three 00:58 into 3 into 11 01:01 into 1 0 1 i hope this is clear to you 01:05 if you yet have any doubts please let me 01:07 know in the comments below and i'll get 01:08 back to you as soon as possible 01:10 also please like the video and subscribe 01:12 the channel thank you so much guys Was This helpful?
Introduction to the Number System
The number system is the method for representing numbers. A number system is a writing system used to describe numbers. Number System For example, numbers with three digits start with 100 i.e. smallest 3-digit number and end with 999 i.e. the greatest 3-digit number. These numbers have three digits, the first of which must be one or greater, and the remaining three may range from zero to nine. The foundation for higher-digit numbers is learning 3-digit numbers. Let's know more about smallest and greatest 3-digit number also the significance, structure, and place value of up to three-digit numbers. What Are Three-Digit Numbers That Exist?Numbers with three digits are known as 3-digit numbers. They begin at 100 and continue to 999. Consider the following examples of three-digit numbers in the ones, tens, and hundred positions. Place Value of Digits Examples of 3-digit numbers are 673, 104, and, 985. A three-digit number cannot have zero as its first digit because that would turn it into a two-digit number. Essential Facts about Three-Digit Numbers
Common Mistakes with Three-Digit Numbers
Tips to Get the Smallest and Largest Numbers The Smallest 3-Digit NumberThe smallest 3-digit number is 100 because its predecessor is 999, a two-digit number. Smallest Three-digit Numbers Three-digit numbers begin at 100 and end at 999. The Largest 3-Digit NumberThe largest 3-digit number is 999 because 1000 is a four-digit number. It is because three-digit numbers begin at 100 and end at 999. A Largest Three-digit Number The Expanded Form of Three-Digit NumbersA three-digit number can be expressed and written in three different ways. Take the three-digit number 457. 457 can be written in one of two ways: 457 = (4 hundreds) + (5 tens) + (7 ones). In another way 457 can be written as 457 = (4 x 100) + (5 x 10) + (7 x 1). Finally, the number 457 can be expanded as 457 = 400 + 50 + 7. All three expanded form number writing methods are correct. Writing a three-digit number in its expanded form aids in understanding its constituents. Essentially, splitting or expanding a 3-digit number helps us understand more about the 3-digit number. By breaking, we know the number of hundreds, tens, and units available in the 3-digit number. SummaryLearning about different digits is fun and gives us more knowledge. We can learn about the smallest and largest numbers if we know the common tricks to get the three-digit most significant and minor numbers. A number system is a way to describe numbers. Mathematical notation is a set of digits or symbols used to express a series of numbers. In addition to division, multiplication, and subtraction, it allows us to carry out arithmetic operations. For example, numbers with three digits start with 100 and end with 999. These numbers have three digits, the first of which must be one or greater, and the remaining three may range from zero to nine. What is the largest 4 digit number and 3 digit number?The greatest 4-digit number with 3 different digits is 9987
