Given numbers are 506, 561, 489, 270

The list of prime factors of all numbers are

Prime factors of 506 are 2 x 11 x 23

Prime factors of 561 are 3 x 11 x 17

Prime factors of 489 are 3 x 163

Prime factors of 270 are 2 x 3 x 3 x 3 x 5

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

Given numbers are 506, 561, 489, 270

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

Apply this formula for all numbers.

Step1:

LCM(506, 561) = 25806

GCD(506, 561) = ( 506 x 561 ) / 25806

= 506 / 561

= 506

Step2:

LCM(11, 489) = 5379

GCD(11, 489) = ( 11 x 489 ) / 5379

= 11 / 489

= 11

Step3:

LCM(1, 270) = 270

GCD(1, 270) = ( 1 x 270 ) / 270

= 1 / 270

= 1

So, Greatest Common Divisor of 506, 561, 489, 270 is 1
