Given numbers are 489, 618, 356, 280

The list of prime factors of all numbers are

Prime factors of 489 are 3 x 163

Prime factors of 618 are 2 x 3 x 103

Prime factors of 356 are 2 x 2 x 89

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 489, 618, 356, 280

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

Apply this formula for all numbers.

Step1:

LCM(489, 618) = 100734

GCD(489, 618) = ( 489 x 618 ) / 100734

= 489 / 618

= 489

Step2:

LCM(3, 356) = 1068

GCD(3, 356) = ( 3 x 356 ) / 1068

= 3 / 356

= 3

Step3:

LCM(1, 280) = 280

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

= 1 / 280

= 1

So, Greatest Common Divisor of 489, 618, 356, 280 is 1
