Given numbers are 666, 432, 772, 155

The list of prime factors of all numbers are

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

Prime factors of 432 are 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 772 are 2 x 2 x 193

Prime factors of 155 are 5 x 31

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

Given numbers are 666, 432, 772, 155

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

Apply this formula for all numbers.

Step1:

LCM(666, 432) = 15984

GCD(666, 432) = ( 666 x 432 ) / 15984

= 666 / 432

= 666

Step2:

LCM(18, 772) = 6948

GCD(18, 772) = ( 18 x 772 ) / 6948

= 18 / 772

= 18

Step3:

LCM(2, 155) = 310

GCD(2, 155) = ( 2 x 155 ) / 310

= 2 / 155

= 2

So, Greatest Common Divisor of 666, 432, 772, 155 is 1
