Given numbers are 579, 660, 515, 345

The list of prime factors of all numbers are

Prime factors of 579 are 3 x 193

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 515 are 5 x 103

Prime factors of 345 are 3 x 5 x 23

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

Given numbers are 579, 660, 515, 345

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

Apply this formula for all numbers.

Step1:

LCM(579, 660) = 127380

GCD(579, 660) = ( 579 x 660 ) / 127380

= 579 / 660

= 579

Step2:

LCM(3, 515) = 1545

GCD(3, 515) = ( 3 x 515 ) / 1545

= 3 / 515

= 3

Step3:

LCM(1, 345) = 345

GCD(1, 345) = ( 1 x 345 ) / 345

= 1 / 345

= 1

So, Greatest Common Divisor of 579, 660, 515, 345 is 1
