Given numbers are 555, 591, 442, 640

The list of prime factors of all numbers are

Prime factors of 555 are 3 x 5 x 37

Prime factors of 591 are 3 x 197

Prime factors of 442 are 2 x 13 x 17

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

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

Given numbers are 555, 591, 442, 640

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

Apply this formula for all numbers.

Step1:

LCM(555, 591) = 109335

GCD(555, 591) = ( 555 x 591 ) / 109335

= 555 / 591

= 555

Step2:

LCM(3, 442) = 1326

GCD(3, 442) = ( 3 x 442 ) / 1326

= 3 / 442

= 3

Step3:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

So, Greatest Common Divisor of 555, 591, 442, 640 is 1
