Answer 1

Ascertain the prime and unknown quantity factors of both expressions.

40a3b = 2 x 2 x 2 x 5 x a x 3 x b = 23 x 3 x 5 x a x b.

24a3b5 = 2 x 2 x 2 x 3 x a x 3 x b x 5 = 23 x 32 x 5 x a x b.

The common factors are 23, 3, 5, a and b

The Greatest Common Factor is 23 x 3 x 5 x a x b = 120ab = 40a3b

Answer 2
