Given numbers are 721, 870, 591, 510

The list of prime factors of all numbers are

Prime factors of 721 are 7 x 103

Prime factors of 870 are 2 x 3 x 5 x 29

Prime factors of 591 are 3 x 197

Prime factors of 510 are 2 x 3 x 5 x 17

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

Given numbers are 721, 870, 591, 510

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

Apply this formula for all numbers.

Step1:

LCM(721, 870) = 627270

GCD(721, 870) = ( 721 x 870 ) / 627270

= 721 / 870

= 721

Step2:

LCM(1, 591) = 591

GCD(1, 591) = ( 1 x 591 ) / 591

= 1 / 591

= 1

Step3:

LCM(1, 510) = 510

GCD(1, 510) = ( 1 x 510 ) / 510

= 1 / 510

= 1

So, Greatest Common Divisor of 721, 870, 591, 510 is 1
