Given numbers are 662, 855, 312, 665

The list of prime factors of all numbers are

Prime factors of 662 are 2 x 331

Prime factors of 855 are 3 x 3 x 5 x 19

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

Prime factors of 665 are 5 x 7 x 19

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

Given numbers are 662, 855, 312, 665

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

Apply this formula for all numbers.

Step1:

LCM(662, 855) = 566010

GCD(662, 855) = ( 662 x 855 ) / 566010

= 662 / 855

= 662

Step2:

LCM(1, 312) = 312

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

= 1 / 312

= 1

Step3:

LCM(1, 665) = 665

GCD(1, 665) = ( 1 x 665 ) / 665

= 1 / 665

= 1

So, Greatest Common Divisor of 662, 855, 312, 665 is 1
