Given numbers are 378, 646, 924, 417

The list of prime factors of all numbers are

Prime factors of 378 are 2 x 3 x 3 x 3 x 7

Prime factors of 646 are 2 x 17 x 19

Prime factors of 924 are 2 x 2 x 3 x 7 x 11

Prime factors of 417 are 3 x 139

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

Given numbers are 378, 646, 924, 417

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

Apply this formula for all numbers.

Step1:

LCM(378, 646) = 122094

GCD(378, 646) = ( 378 x 646 ) / 122094

= 378 / 646

= 378

Step2:

LCM(2, 924) = 924

GCD(2, 924) = ( 2 x 924 ) / 924

= 2 / 924

= 2

Step3:

LCM(2, 417) = 834

GCD(2, 417) = ( 2 x 417 ) / 834

= 2 / 417

= 2

So, Greatest Common Divisor of 378, 646, 924, 417 is 1
