Answer 1

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!

Answer 2

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.
