Given numbers are 640, 872, 554, 111

The list of prime factors of all numbers are

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 872 are 2 x 2 x 2 x 109

Prime factors of 554 are 2 x 277

Prime factors of 111 are 3 x 37

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

Given numbers are 640, 872, 554, 111

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

Apply this formula for all numbers.

Step1:

LCM(640, 872) = 69760

GCD(640, 872) = ( 640 x 872 ) / 69760

= 640 / 872

= 640

Step2:

LCM(8, 554) = 2216

GCD(8, 554) = ( 8 x 554 ) / 2216

= 8 / 554

= 8

Step3:

LCM(2, 111) = 222

GCD(2, 111) = ( 2 x 111 ) / 222

= 2 / 111

= 2

So, Greatest Common Divisor of 640, 872, 554, 111 is 1
