Given numbers are 555, 666, 628, 210

The list of prime factors of all numbers are

Prime factors of 555 are 3 x 5 x 37

Prime factors of 666 are 2 x 3 x 3 x 37

Prime factors of 628 are 2 x 2 x 157

Prime factors of 210 are 2 x 3 x 5 x 7

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

Given numbers are 555, 666, 628, 210

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

Apply this formula for all numbers.

Step1:

LCM(555, 666) = 3330

GCD(555, 666) = ( 555 x 666 ) / 3330

= 555 / 666

= 555

Step2:

LCM(111, 628) = 69708

GCD(111, 628) = ( 111 x 628 ) / 69708

= 111 / 628

= 111

Step3:

LCM(1, 210) = 210

GCD(1, 210) = ( 1 x 210 ) / 210

= 1 / 210

= 1

So, Greatest Common Divisor of 555, 666, 628, 210 is 1
