Given numbers are 390, 528, 261, 556

The list of prime factors of all numbers are

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 528 are 2 x 2 x 2 x 2 x 3 x 11

Prime factors of 261 are 3 x 3 x 29

Prime factors of 556 are 2 x 2 x 139

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

Given numbers are 390, 528, 261, 556

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

Apply this formula for all numbers.

Step1:

LCM(390, 528) = 34320

GCD(390, 528) = ( 390 x 528 ) / 34320

= 390 / 528

= 390

Step2:

LCM(6, 261) = 522

GCD(6, 261) = ( 6 x 261 ) / 522

= 6 / 261

= 6

Step3:

LCM(3, 556) = 1668

GCD(3, 556) = ( 3 x 556 ) / 1668

= 3 / 556

= 3

So, Greatest Common Divisor of 390, 528, 261, 556 is 1
