Given numbers are 515, 579, 520, 648

The list of prime factors of all numbers are

Prime factors of 515 are 5 x 103

Prime factors of 579 are 3 x 193

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

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

Given numbers are 515, 579, 520, 648

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

Apply this formula for all numbers.

Step1:

LCM(515, 579) = 298185

GCD(515, 579) = ( 515 x 579 ) / 298185

= 515 / 579

= 515

Step2:

LCM(1, 520) = 520

GCD(1, 520) = ( 1 x 520 ) / 520

= 1 / 520

= 1

Step3:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

So, Greatest Common Divisor of 515, 579, 520, 648 is 1
