Given numbers are 639, 784, 267, 812

The list of prime factors of all numbers are

Prime factors of 639 are 3 x 3 x 71

Prime factors of 784 are 2 x 2 x 2 x 2 x 7 x 7

Prime factors of 267 are 3 x 89

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 639, 784, 267, 812

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

Apply this formula for all numbers.

Step1:

LCM(639, 784) = 500976

GCD(639, 784) = ( 639 x 784 ) / 500976

= 639 / 784

= 639

Step2:

LCM(1, 267) = 267

GCD(1, 267) = ( 1 x 267 ) / 267

= 1 / 267

= 1

Step3:

LCM(1, 812) = 812

GCD(1, 812) = ( 1 x 812 ) / 812

= 1 / 812

= 1

So, Greatest Common Divisor of 639, 784, 267, 812 is 1
