Given numbers are 671, 280, 130, 489

The list of prime factors of all numbers are

Prime factors of 671 are 11 x 61

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 130 are 2 x 5 x 13

Prime factors of 489 are 3 x 163

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

Given numbers are 671, 280, 130, 489

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

Apply this formula for all numbers.

Step1:

LCM(671, 280) = 187880

GCD(671, 280) = ( 671 x 280 ) / 187880

= 671 / 280

= 671

Step2:

LCM(1, 130) = 130

GCD(1, 130) = ( 1 x 130 ) / 130

= 1 / 130

= 1

Step3:

LCM(1, 489) = 489

GCD(1, 489) = ( 1 x 489 ) / 489

= 1 / 489

= 1

So, Greatest Common Divisor of 671, 280, 130, 489 is 1
