Given numbers are 721, 188, 355, 556

The list of prime factors of all numbers are

Prime factors of 721 are 7 x 103

Prime factors of 188 are 2 x 2 x 47

Prime factors of 355 are 5 x 71

Prime factors of 556 are 2 x 2 x 139

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

Given numbers are 721, 188, 355, 556

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

Apply this formula for all numbers.

Step1:

LCM(721, 188) = 135548

GCD(721, 188) = ( 721 x 188 ) / 135548

= 721 / 188

= 721

Step2:

LCM(1, 355) = 355

GCD(1, 355) = ( 1 x 355 ) / 355

= 1 / 355

= 1

Step3:

LCM(1, 556) = 556

GCD(1, 556) = ( 1 x 556 ) / 556

= 1 / 556

= 1

So, Greatest Common Divisor of 721, 188, 355, 556 is 1
