GCD of numbers is the greatest common divisor

So, the GCD (120, 646, 45, 666) = 1.

Given numbers are 120, 646, 45, 666

The list of prime factors of all numbers are

Prime factors of 120 are 2 x 2 x 2 x 3 x 5

Prime factors of 646 are 2 x 17 x 19

Prime factors of 45 are 3 x 3 x 5

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

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

Given numbers are 120, 646, 45, 666

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

Apply this formula for all numbers.

Step1:

LCM(120, 646) = 38760

GCD(120, 646) = ( 120 x 646 ) / 38760

= 120 / 646

= 120

Step2:

LCM(2, 45) = 90

GCD(2, 45) = ( 2 x 45 ) / 90

= 2 / 45

= 2

Step3:

LCM(1, 666) = 666

GCD(1, 666) = ( 1 x 666 ) / 666

= 1 / 666

= 1

So, Greatest Common Divisor of 120, 646, 45, 666 is 1
