Q1 B of 42 Page 136

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

5p2q2, 10p2q2, 25p4q3


factors of 5p2q2=5×p×p×q×q


factors of 10p2q2=2×5×p×p×q×q


factors of 25p4q3=2×2×5×5×p×q×q×q


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


∴the GCD of 5p2q2, 10p2q2, 25p4q3 is 5pq2
