Given numbers are 555, 510, 648, 977

The list of prime factors of all numbers are

Prime factors of 555 are 3 x 5 x 37

Prime factors of 510 are 2 x 3 x 5 x 17

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 977 are 977

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

Given numbers are 555, 510, 648, 977

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

Apply this formula for all numbers.

Step1:

LCM(555, 510) = 18870

GCD(555, 510) = ( 555 x 510 ) / 18870

= 555 / 510

= 555

Step2:

LCM(15, 648) = 3240

GCD(15, 648) = ( 15 x 648 ) / 3240

= 15 / 648

= 15

Step3:

LCM(3, 977) = 2931

GCD(3, 977) = ( 3 x 977 ) / 2931

= 3 / 977

= 3

So, Greatest Common Divisor of 555, 510, 648, 977 is 1
