Given numbers are 207, 774, 665, 312

The list of prime factors of all numbers are

Prime factors of 207 are 3 x 3 x 23

Prime factors of 774 are 2 x 3 x 3 x 43

Prime factors of 665 are 5 x 7 x 19

Prime factors of 312 are 2 x 2 x 2 x 3 x 13

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

Given numbers are 207, 774, 665, 312

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

Apply this formula for all numbers.

Step1:

LCM(207, 774) = 17802

GCD(207, 774) = ( 207 x 774 ) / 17802

= 207 / 774

= 207

Step2:

LCM(9, 665) = 5985

GCD(9, 665) = ( 9 x 665 ) / 5985

= 9 / 665

= 9

Step3:

LCM(1, 312) = 312

GCD(1, 312) = ( 1 x 312 ) / 312

= 1 / 312

= 1

So, Greatest Common Divisor of 207, 774, 665, 312 is 1
