Given numbers are 654, 518, 555, 668

The list of prime factors of all numbers are

Prime factors of 654 are 2 x 3 x 109

Prime factors of 518 are 2 x 7 x 37

Prime factors of 555 are 3 x 5 x 37

Prime factors of 668 are 2 x 2 x 167

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

Given numbers are 654, 518, 555, 668

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

Apply this formula for all numbers.

Step1:

LCM(654, 518) = 169386

GCD(654, 518) = ( 654 x 518 ) / 169386

= 654 / 518

= 654

Step2:

LCM(2, 555) = 1110

GCD(2, 555) = ( 2 x 555 ) / 1110

= 2 / 555

= 2

Step3:

LCM(1, 668) = 668

GCD(1, 668) = ( 1 x 668 ) / 668

= 1 / 668

= 1

So, Greatest Common Divisor of 654, 518, 555, 668 is 1
