Given numbers are 647, 666, 620, 504

The list of prime factors of all numbers are

Prime factors of 647 are 647

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

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 504 are 2 x 2 x 2 x 3 x 3 x 7

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

Given numbers are 647, 666, 620, 504

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

Apply this formula for all numbers.

Step1:

LCM(647, 666) = 430902

GCD(647, 666) = ( 647 x 666 ) / 430902

= 647 / 666

= 647

Step2:

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

= 1 / 620

= 1

Step3:

LCM(1, 504) = 504

GCD(1, 504) = ( 1 x 504 ) / 504

= 1 / 504

= 1

So, Greatest Common Divisor of 647, 666, 620, 504 is 1
