Given numbers are 438, 828, 454, 921

The list of prime factors of all numbers are

Prime factors of 438 are 2 x 3 x 73

Prime factors of 828 are 2 x 2 x 3 x 3 x 23

Prime factors of 454 are 2 x 227

Prime factors of 921 are 3 x 307

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

Given numbers are 438, 828, 454, 921

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

Apply this formula for all numbers.

Step1:

LCM(438, 828) = 60444

GCD(438, 828) = ( 438 x 828 ) / 60444

= 438 / 828

= 438

Step2:

LCM(6, 454) = 1362

GCD(6, 454) = ( 6 x 454 ) / 1362

= 6 / 454

= 6

Step3:

LCM(2, 921) = 1842

GCD(2, 921) = ( 2 x 921 ) / 1842

= 2 / 921

= 2

So, Greatest Common Divisor of 438, 828, 454, 921 is 1
