Given numbers are 378, 903, 921, 812

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 903 are 3 x 7 x 43

Prime factors of 921 are 3 x 307

Prime factors of 812 are 2 x 2 x 7 x 29

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

Given numbers are 378, 903, 921, 812

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

Apply this formula for all numbers.

Step1:

LCM(378, 903) = 16254

GCD(378, 903) = ( 378 x 903 ) / 16254

= 378 / 903

= 378

Step2:

LCM(21, 921) = 6447

GCD(21, 921) = ( 21 x 921 ) / 6447

= 21 / 921

= 21

Step3:

LCM(3, 812) = 2436

GCD(3, 812) = ( 3 x 812 ) / 2436

= 3 / 812

= 3

So, Greatest Common Divisor of 378, 903, 921, 812 is 1
