The list of prime factors of all numbers are
Prime factors of 721 are 7 x 103
Prime factors of 616 are 2 x 2 x 2 x 7 x 11
Prime factors of 627 are 3 x 11 x 19
Prime factors of 625 are 5 x 5 x 5 x 5
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 721, 616, 627, 625
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(721, 616) = 63448
GCD(721, 616) = ( 721 x 616 ) / 63448
= 721 / 616
= 721
Step2:
LCM(7, 627) = 4389
GCD(7, 627) = ( 7 x 627 ) / 4389
= 7 / 627
= 7
Step3:
LCM(1, 625) = 625
GCD(1, 625) = ( 1 x 625 ) / 625
= 1 / 625
= 1
So, Greatest Common Divisor of 721, 616, 627, 625 is 1
