Given numbers are 945, 324, 363, 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 324 are 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 363 are 3 x 11 x 11

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, 324, 363, 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, 324) = 11340

GCD(945, 324) = ( 945 x 324 ) / 11340

= 945 / 324

= 945

Step2:

LCM(27, 363) = 3267

GCD(27, 363) = ( 27 x 363 ) / 3267

= 27 / 363

= 27

Step3:

LCM(3, 646) = 1938

GCD(3, 646) = ( 3 x 646 ) / 1938

= 3 / 646

= 3

So, Greatest Common Divisor of 945, 324, 363, 646 is 1
