Given numbers are 393, 204, 615, 970

The list of prime factors of all numbers are

Prime factors of 393 are 3 x 131

Prime factors of 204 are 2 x 2 x 3 x 17

Prime factors of 615 are 3 x 5 x 41

Prime factors of 970 are 2 x 5 x 97

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

Given numbers are 393, 204, 615, 970

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

Apply this formula for all numbers.

Step1:

LCM(393, 204) = 26724

GCD(393, 204) = ( 393 x 204 ) / 26724

= 393 / 204

= 393

Step2:

LCM(3, 615) = 615

GCD(3, 615) = ( 3 x 615 ) / 615

= 3 / 615

= 3

Step3:

LCM(3, 970) = 2910

GCD(3, 970) = ( 3 x 970 ) / 2910

= 3 / 970

= 3

So, Greatest Common Divisor of 393, 204, 615, 970 is 1
