Given numbers are 122, 621, 472, 520

The list of prime factors of all numbers are

Prime factors of 122 are 2 x 61

Prime factors of 621 are 3 x 3 x 3 x 23

Prime factors of 472 are 2 x 2 x 2 x 59

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 122, 621, 472, 520

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

Apply this formula for all numbers.

Step1:

LCM(122, 621) = 75762

GCD(122, 621) = ( 122 x 621 ) / 75762

= 122 / 621

= 122

Step2:

LCM(1, 472) = 472

GCD(1, 472) = ( 1 x 472 ) / 472

= 1 / 472

= 1

Step3:

LCM(1, 520) = 520

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

= 1 / 520

= 1

So, Greatest Common Divisor of 122, 621, 472, 520 is 1
