Given numbers are 312, 507, 217, 765

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 507 are 3 x 13 x 13

Prime factors of 217 are 7 x 31

Prime factors of 765 are 3 x 3 x 5 x 17

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

Given numbers are 312, 507, 217, 765

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

Apply this formula for all numbers.

Step1:

LCM(312, 507) = 4056

GCD(312, 507) = ( 312 x 507 ) / 4056

= 312 / 507

= 312

Step2:

LCM(39, 217) = 8463

GCD(39, 217) = ( 39 x 217 ) / 8463

= 39 / 217

= 39

Step3:

LCM(1, 765) = 765

GCD(1, 765) = ( 1 x 765 ) / 765

= 1 / 765

= 1

So, Greatest Common Divisor of 312, 507, 217, 765 is 1
