Question

Find the GCM, 28c^2d^3,14c^3d^2,42cd^2

Answer 1

GCF of (28,14, and 42) = 14
GCF of (c^2d^3, c^3d^2, and cd^2) = cd^2
then multiply them, get 14cd^2

Answer 2

can you show me how you work it out?
How you get the factors of 28, 14, and 42?

Answer 3

GCM = GCF = HCF = the highest divisor.
28, 14, 42 can divided by 14, right ? so we find the a number which can divides the numbers above
