Given numbers are 105, 556, 617, 672

The list of prime factors of all numbers are

Prime factors of 105 are 3 x 5 x 7

Prime factors of 556 are 2 x 2 x 139

Prime factors of 617 are 617

Prime factors of 672 are 2 x 2 x 2 x 2 x 2 x 3 x 7

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

Given numbers are 105, 556, 617, 672

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

Apply this formula for all numbers.

Step1:

LCM(105, 556) = 58380

GCD(105, 556) = ( 105 x 556 ) / 58380

= 105 / 556

= 105

Step2:

LCM(1, 617) = 617

GCD(1, 617) = ( 1 x 617 ) / 617

= 1 / 617

= 1

Step3:

LCM(1, 672) = 672

GCD(1, 672) = ( 1 x 672 ) / 672

= 1 / 672

= 1

So, Greatest Common Divisor of 105, 556, 617, 672 is 1
