Hey guys, for the people who are actually looking this up do it yourself and dont be lazy!, But today i will be nice and tell you the GCF for 42 and 50 is 200. If you think i think your lazy and told you the wrong answer heres a example.

Example HERE-

42- 42, 84, 116, 158, 200

50- 50, 100, 150, 200 :)

The above is a load of bouncing objects.

The Greatest Common Factor is 2: (2 x 3 x 7) and (2 x 5 x 5).

The Lowest Common Multiple of 42 and 50 is 1050. (25 x 42, 21 x 50).

It's worth pointing out that 84 + 42 is 126, not 116.

I wish eejits wouldn't effaboot wi' ma answers!

To find the GCF of two numbers you can find the factor pairs of each and then find the factors they have in common.

50:

1 x 50

2 x 25

5 x 10

42:

1 x 42

2 x 21

3 x 14

6 x 7

The common factors are: 1 and 2. 2 is the GCF.
