Given numbers are 520, 251, 220, 409

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 251 are 251

Prime factors of 220 are 2 x 2 x 5 x 11

Prime factors of 409 are 409

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

Given numbers are 520, 251, 220, 409

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

Apply this formula for all numbers.

Step1:

LCM(520, 251) = 130520

GCD(520, 251) = ( 520 x 251 ) / 130520

= 520 / 251

= 520

Step2:

LCM(1, 220) = 220

GCD(1, 220) = ( 1 x 220 ) / 220

= 1 / 220

= 1

Step3:

LCM(1, 409) = 409

GCD(1, 409) = ( 1 x 409 ) / 409

= 1 / 409

= 1

So, Greatest Common Divisor of 520, 251, 220, 409 is 1
