Write down all factors of 18 and 24
To find the factors of a number, you need to determine all the numbers that divide evenly into that number.
Let's start with 18:
The factors of 18 are: 1, 2, 3, 6, 9, and 18.
To determine the factors, you can start dividing the number by smaller numbers and check if the division is exact (with no remainder). You begin with 1 and incrementally go up to the square root of 18 (which is approximately 4.24). In this case, 4 is the largest whole number that divides 18, so we find the other factors by dividing 18 by the numbers 2, 3, 6, 9, and 18.
Now let's find the factors of 24:
The factors of 24 are: 1, 2, 3, 4, 6, 8, 12, and 24.
Similarly, you start dividing 24 by smaller numbers and go up to the square root of 24 (which is approximately 4.9). The largest whole number that divides 24 is 4, so we divide 24 by the numbers 2, 3, 4, 6, 8, 12, and 24 to find all the factors.
So, the factors of 18 are 1, 2, 3, 6, 9, and 18, while the factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24.
