Given numbers are 972, 663, 930, 680

The list of prime factors of all numbers are

Prime factors of 972 are 2 x 2 x 3 x 3 x 3 x 3 x 3

Prime factors of 663 are 3 x 13 x 17

Prime factors of 930 are 2 x 3 x 5 x 31

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

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

Given numbers are 972, 663, 930, 680

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

Apply this formula for all numbers.

Step1:

LCM(972, 663) = 214812

GCD(972, 663) = ( 972 x 663 ) / 214812

= 972 / 663

= 972

Step2:

LCM(3, 930) = 930

GCD(3, 930) = ( 3 x 930 ) / 930

= 3 / 930

= 3

Step3:

LCM(3, 680) = 2040

GCD(3, 680) = ( 3 x 680 ) / 2040

= 3 / 680

= 3

So, Greatest Common Divisor of 972, 663, 930, 680 is 1
