Given numbers are 666, 129, 615, 620

The list of prime factors of all numbers are

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

Prime factors of 129 are 3 x 43

Prime factors of 615 are 3 x 5 x 41

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

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

Given numbers are 666, 129, 615, 620

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

Apply this formula for all numbers.

Step1:

LCM(666, 129) = 28638

GCD(666, 129) = ( 666 x 129 ) / 28638

= 666 / 129

= 666

Step2:

LCM(3, 615) = 615

GCD(3, 615) = ( 3 x 615 ) / 615

= 3 / 615

= 3

Step3:

LCM(3, 620) = 1860

GCD(3, 620) = ( 3 x 620 ) / 1860

= 3 / 620

= 3

So, Greatest Common Divisor of 666, 129, 615, 620 is 1
