Q1 C of 42 Page 136

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

7y3z6, 21y2, 14z2


factors of 7y3z6=7×y×y×y×z×z×z×z×z×z


Factors of 21y2=3×7×y×y


Factors of 14z2=2×7×z×z


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


∴ the GCD of 7y3z6, 21y2, 14z2 is 7
