Given numbers are 981, 530, 710, 648

The list of prime factors of all numbers are

Prime factors of 981 are 3 x 3 x 109

Prime factors of 530 are 2 x 5 x 53

Prime factors of 710 are 2 x 5 x 71

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 981, 530, 710, 648

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(981, 530) = 519930

GCD(981, 530) = ( 981 x 530 ) / 519930

= 981 / 530

= 981

Step2:

LCM(1, 710) = 710

GCD(1, 710) = ( 1 x 710 ) / 710

= 1 / 710

= 1

Step3:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

So, Greatest Common Divisor of 981, 530, 710, 648 is 1
