Given numbers are 520, 212, 685, 311

The list of prime factors of all numbers are

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

Prime factors of 212 are 2 x 2 x 53

Prime factors of 685 are 5 x 137

Prime factors of 311 are 311

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

Given numbers are 520, 212, 685, 311

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

Apply this formula for all numbers.

Step1:

LCM(520, 212) = 27560

GCD(520, 212) = ( 520 x 212 ) / 27560

= 520 / 212

= 520

Step2:

LCM(4, 685) = 2740

GCD(4, 685) = ( 4 x 685 ) / 2740

= 4 / 685

= 4

Step3:

LCM(1, 311) = 311

GCD(1, 311) = ( 1 x 311 ) / 311

= 1 / 311

= 1

So, Greatest Common Divisor of 520, 212, 685, 311 is 1
