Answer 1

Step-bPut simply, the GCF of a set of whole numbers is the largest positive integer (i.e whole number and not a decimal) that divides evenly into all of the numbers in the set. It's also commonly known as:

Greatest Common Denominator (GCD)

Highest Common Factor (HCF)

Greatest Common Divisor (GCD)

There are a number of different ways to calculate the GCF of a set of numbers depending how many numbers you have and how large they are.

For smaller numbers you can simply look at the factors or multiples for each number and find the greatest common multiple of them.

For 423, 238, and 462 those factors look like this:

Factors for 423: 1, 3, 9, 47, 141, and 423

Factors for 238: 1, 2, 7, 14, 17, 34, 119, and 238

Factors for 462: 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, and 462

As you can see when you list out the factors of each number, 1 is the greatest numbery-step explanation:

Answer 2

it would be 2

Explanation:

Divide the larger numbers by the smallest ones and see what fits since its the lcm start at the smallest number and divide
