Given numbers are 378, 231, 920, 676

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 231 are 3 x 7 x 11

Prime factors of 920 are 2 x 2 x 2 x 5 x 23

Prime factors of 676 are 2 x 2 x 13 x 13

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

Given numbers are 378, 231, 920, 676

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

Apply this formula for all numbers.

Step1:

LCM(378, 231) = 4158

GCD(378, 231) = ( 378 x 231 ) / 4158

= 378 / 231

= 378

Step2:

LCM(21, 920) = 19320

GCD(21, 920) = ( 21 x 920 ) / 19320

= 21 / 920

= 21

Step3:

LCM(1, 676) = 676

GCD(1, 676) = ( 1 x 676 ) / 676

= 1 / 676

= 1

So, Greatest Common Divisor of 378, 231, 920, 676 is 1
