Given numbers are 666, 646, 305, 653

The list of prime factors of all numbers are

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

Prime factors of 646 are 2 x 17 x 19

Prime factors of 305 are 5 x 61

Prime factors of 653 are 653

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

Given numbers are 666, 646, 305, 653

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

Apply this formula for all numbers.

Step1:

LCM(666, 646) = 215118

GCD(666, 646) = ( 666 x 646 ) / 215118

= 666 / 646

= 666

Step2:

LCM(2, 305) = 610

GCD(2, 305) = ( 2 x 305 ) / 610

= 2 / 305

= 2

Step3:

LCM(1, 653) = 653

GCD(1, 653) = ( 1 x 653 ) / 653

= 1 / 653

= 1

So, Greatest Common Divisor of 666, 646, 305, 653 is 1
