Given numbers are 128, 123, 618

The list of prime factors of all numbers are

Prime factors of 128 are 2 x 2 x 2 x 2 x 2 x 2 x 2

Prime factors of 123 are 3 x 41

Prime factors of 618 are 2 x 3 x 103

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

Given numbers are 128, 123, 618

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

Apply this formula for all numbers.

Step1:

LCM(128, 123) = 15744

GCD(128, 123) = ( 128 x 123 ) / 15744

= 128 / 123

= 128

Step2:

LCM(1, 618) = 618

GCD(1, 618) = ( 1 x 618 ) / 618

= 1 / 618

= 1

So, Greatest Common Divisor of 128, 123, 618 is 1
