Given numbers are 660, 955, 502, 390

The list of prime factors of all numbers are

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 955 are 5 x 191

Prime factors of 502 are 2 x 251

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

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

Given numbers are 660, 955, 502, 390

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

Apply this formula for all numbers.

Step1:

LCM(660, 955) = 126060

GCD(660, 955) = ( 660 x 955 ) / 126060

= 660 / 955

= 660

Step2:

LCM(5, 502) = 2510

GCD(5, 502) = ( 5 x 502 ) / 2510

= 5 / 502

= 5

Step3:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

So, Greatest Common Divisor of 660, 955, 502, 390 is 1
