Given numbers are 267, 720, 379, 639

The list of prime factors of all numbers are

Prime factors of 267 are 3 x 89

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 379 are 379

Prime factors of 639 are 3 x 3 x 71

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

Given numbers are 267, 720, 379, 639

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

Apply this formula for all numbers.

Step1:

LCM(267, 720) = 64080

GCD(267, 720) = ( 267 x 720 ) / 64080

= 267 / 720

= 267

Step2:

LCM(3, 379) = 1137

GCD(3, 379) = ( 3 x 379 ) / 1137

= 3 / 379

= 3

Step3:

LCM(1, 639) = 639

GCD(1, 639) = ( 1 x 639 ) / 639

= 1 / 639

= 1

So, Greatest Common Divisor of 267, 720, 379, 639 is 1
