# Let’s find G.C.D of the following algebraic expressions:

7y^{3}z_{6}, 21y^{2}, 14z^{2}

Answer :

factors of 7y^{3}z^{6}=7×y×y×y×z×z×z×z×z×z

Factors of 21y^{2}=3×7×y×y

Factors of 14z^{2}=2×7×z×z

GCD is the greatest common divisor, which is equal to the product of all the common divisors.

∴ the GCD of 7y^{3}z^{6}, 21y^{2}, 14z^{2} is 7
