Given numbers are 312, 639, 531, 845

The list of prime factors of all numbers are

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

Prime factors of 639 are 3 x 3 x 71

Prime factors of 531 are 3 x 3 x 59

Prime factors of 845 are 5 x 13 x 13

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

Given numbers are 312, 639, 531, 845

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

Apply this formula for all numbers.

Step1:

LCM(312, 639) = 66456

GCD(312, 639) = ( 312 x 639 ) / 66456

= 312 / 639

= 312

Step2:

LCM(3, 531) = 531

GCD(3, 531) = ( 3 x 531 ) / 531

= 3 / 531

= 3

Step3:

LCM(3, 845) = 2535

GCD(3, 845) = ( 3 x 845 ) / 2535

= 3 / 845

= 3

So, Greatest Common Divisor of 312, 639, 531, 845 is 1
