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
