Given numbers are 721, 311, 518, 520

The list of prime factors of all numbers are

Prime factors of 721 are 7 x 103

Prime factors of 311 are 311

Prime factors of 518 are 2 x 7 x 37

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

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

Given numbers are 721, 311, 518, 520

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

Apply this formula for all numbers.

Step1:

LCM(721, 311) = 224231

GCD(721, 311) = ( 721 x 311 ) / 224231

= 721 / 311

= 721

Step2:

LCM(1, 518) = 518

GCD(1, 518) = ( 1 x 518 ) / 518

= 1 / 518

= 1

Step3:

LCM(1, 520) = 520

GCD(1, 520) = ( 1 x 520 ) / 520

= 1 / 520

= 1

So, Greatest Common Divisor of 721, 311, 518, 520 is 1
