Given numbers are 721, 171, 578, 908

The list of prime factors of all numbers are

Prime factors of 721 are 7 x 103

Prime factors of 171 are 3 x 3 x 19

Prime factors of 578 are 2 x 17 x 17

Prime factors of 908 are 2 x 2 x 227

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

Given numbers are 721, 171, 578, 908

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

Apply this formula for all numbers.

Step1:

LCM(721, 171) = 123291

GCD(721, 171) = ( 721 x 171 ) / 123291

= 721 / 171

= 721

Step2:

LCM(1, 578) = 578

GCD(1, 578) = ( 1 x 578 ) / 578

= 1 / 578

= 1

Step3:

LCM(1, 908) = 908

GCD(1, 908) = ( 1 x 908 ) / 908

= 1 / 908

= 1

So, Greatest Common Divisor of 721, 171, 578, 908 is 1
