Given numbers are 945, 380, 957, 646

The list of prime factors of all numbers are

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

Prime factors of 380 are 2 x 2 x 5 x 19

Prime factors of 957 are 3 x 11 x 29

Prime factors of 646 are 2 x 17 x 19

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

Given numbers are 945, 380, 957, 646

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

Apply this formula for all numbers.

Step1:

LCM(945, 380) = 71820

GCD(945, 380) = ( 945 x 380 ) / 71820

= 945 / 380

= 945

Step2:

LCM(5, 957) = 4785

GCD(5, 957) = ( 5 x 957 ) / 4785

= 5 / 957

= 5

Step3:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

So, Greatest Common Divisor of 945, 380, 957, 646 is 1
