Given numbers are 517, 654, 831, 620

The list of prime factors of all numbers are

Prime factors of 517 are 11 x 47

Prime factors of 654 are 2 x 3 x 109

Prime factors of 831 are 3 x 277

Prime factors of 620 are 2 x 2 x 5 x 31

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

Given numbers are 517, 654, 831, 620

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

Apply this formula for all numbers.

Step1:

LCM(517, 654) = 338118

GCD(517, 654) = ( 517 x 654 ) / 338118

= 517 / 654

= 517

Step2:

LCM(1, 831) = 831

GCD(1, 831) = ( 1 x 831 ) / 831

= 1 / 831

= 1

Step3:

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

= 1 / 620

= 1

So, Greatest Common Divisor of 517, 654, 831, 620 is 1
