Given numbers are 277, 586, 645, 520

The list of prime factors of all numbers are

Prime factors of 277 are 277

Prime factors of 586 are 2 x 293

Prime factors of 645 are 3 x 5 x 43

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 277, 586, 645, 520

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

Apply this formula for all numbers.

Step1:

LCM(277, 586) = 162322

GCD(277, 586) = ( 277 x 586 ) / 162322

= 277 / 586

= 277

Step2:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

Step3:

LCM(1, 520) = 520

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

= 1 / 520

= 1

So, Greatest Common Divisor of 277, 586, 645, 520 is 1
