4 & 6: 2, 12

15 & 12: 3, 60

10&14: 2, 70

I gave the answers but you have to figure out how to do the work and show the works for it. Otherwise, your teacher would question you about it.

For instance:

4 = 2 x 2

6 = 2 x 3

The greatest common factor is 2.

64 = 32 x 2

96 = 32 x 3

The GCF is 32. Just factor the two numbers, then take the common factors from among them and multiply them out!

In Mathematics, thjere can be a LEAST COMMON MULTIPLE, which is the smallest number that is divisible by your numbers. An easy way to find this is to factor both numbers, and then thow in what you are missing from one numbner to the other and vice versa:

12 = 4 x 3

8 = 4 x 2

12 lacks a 2, 8 lacks a 3.

4 x 3 x 2 = 24, the least common mutliple.

There are least common multiples; for 4 and 6,

4 8 12 16 20 …

6 12 18 24 30…

12 is the first number in both lists so it’s 12

And greatest common factors; for 4 and 6,

4 = 1,2,4

6 = 1,2,3,6

2 is the greatest number in both lists so 2.

Do the others in a similar way.
