Given numbers are 615, 390, 170, 959

The list of prime factors of all numbers are

Prime factors of 615 are 3 x 5 x 41

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 170 are 2 x 5 x 17

Prime factors of 959 are 7 x 137

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

Given numbers are 615, 390, 170, 959

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

Apply this formula for all numbers.

Step1:

LCM(615, 390) = 15990

GCD(615, 390) = ( 615 x 390 ) / 15990

= 615 / 390

= 615

Step2:

LCM(15, 170) = 510

GCD(15, 170) = ( 15 x 170 ) / 510

= 15 / 170

= 15

Step3:

LCM(5, 959) = 4795

GCD(5, 959) = ( 5 x 959 ) / 4795

= 5 / 959

= 5

So, Greatest Common Divisor of 615, 390, 170, 959 is 1
