Given numbers are 507, 165, 665, 280

The list of prime factors of all numbers are

Prime factors of 507 are 3 x 13 x 13

Prime factors of 165 are 3 x 5 x 11

Prime factors of 665 are 5 x 7 x 19

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

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

Given numbers are 507, 165, 665, 280

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

Apply this formula for all numbers.

Step1:

LCM(507, 165) = 27885

GCD(507, 165) = ( 507 x 165 ) / 27885

= 507 / 165

= 507

Step2:

LCM(3, 665) = 1995

GCD(3, 665) = ( 3 x 665 ) / 1995

= 3 / 665

= 3

Step3:

LCM(1, 280) = 280

GCD(1, 280) = ( 1 x 280 ) / 280

= 1 / 280

= 1

So, Greatest Common Divisor of 507, 165, 665, 280 is 1
