Given numbers are 664, 828, 560, 427

The list of prime factors of all numbers are

Prime factors of 664 are 2 x 2 x 2 x 83

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

Prime factors of 560 are 2 x 2 x 2 x 2 x 5 x 7

Prime factors of 427 are 7 x 61

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

Given numbers are 664, 828, 560, 427

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

Apply this formula for all numbers.

Step1:

LCM(664, 828) = 137448

GCD(664, 828) = ( 664 x 828 ) / 137448

= 664 / 828

= 664

Step2:

LCM(4, 560) = 560

GCD(4, 560) = ( 4 x 560 ) / 560

= 4 / 560

= 4

Step3:

LCM(4, 427) = 1708

GCD(4, 427) = ( 4 x 427 ) / 1708

= 4 / 427

= 4

So, Greatest Common Divisor of 664, 828, 560, 427 is 1
