Given numbers are 520, 390, 957, 166

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 390 are 2 x 3 x 5 x 13

Prime factors of 957 are 3 x 11 x 29

Prime factors of 166 are 2 x 83

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

Given numbers are 520, 390, 957, 166

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

Apply this formula for all numbers.

Step1:

LCM(520, 390) = 1560

GCD(520, 390) = ( 520 x 390 ) / 1560

= 520 / 390

= 520

Step2:

LCM(130, 957) = 124410

GCD(130, 957) = ( 130 x 957 ) / 124410

= 130 / 957

= 130

Step3:

LCM(1, 166) = 166

GCD(1, 166) = ( 1 x 166 ) / 166

= 1 / 166

= 1

So, Greatest Common Divisor of 520, 390, 957, 166 is 1
