Given numbers are 666, 636, 645, 560

The list of prime factors of all numbers are

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

Prime factors of 636 are 2 x 2 x 3 x 53

Prime factors of 645 are 3 x 5 x 43

Prime factors of 560 are 2 x 2 x 2 x 2 x 5 x 7

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

Given numbers are 666, 636, 645, 560

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

Apply this formula for all numbers.

Step1:

LCM(666, 636) = 70596

GCD(666, 636) = ( 666 x 636 ) / 70596

= 666 / 636

= 666

Step2:

LCM(6, 645) = 1290

GCD(6, 645) = ( 6 x 645 ) / 1290

= 6 / 645

= 6

Step3:

LCM(3, 560) = 1680

GCD(3, 560) = ( 3 x 560 ) / 1680

= 3 / 560

= 3

So, Greatest Common Divisor of 666, 636, 645, 560 is 1
