Given numbers are 427, 309, 350, 520

The list of prime factors of all numbers are

Prime factors of 427 are 7 x 61

Prime factors of 309 are 3 x 103

Prime factors of 350 are 2 x 5 x 5 x 7

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 427, 309, 350, 520

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

Apply this formula for all numbers.

Step1:

LCM(427, 309) = 131943

GCD(427, 309) = ( 427 x 309 ) / 131943

= 427 / 309

= 427

Step2:

LCM(1, 350) = 350

GCD(1, 350) = ( 1 x 350 ) / 350

= 1 / 350

= 1

Step3:

LCM(1, 520) = 520

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

= 1 / 520

= 1

So, Greatest Common Divisor of 427, 309, 350, 520 is 1
