Given numbers are 843, 489, 830, 630

The list of prime factors of all numbers are

Prime factors of 843 are 3 x 281

Prime factors of 489 are 3 x 163

Prime factors of 830 are 2 x 5 x 83

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

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

Given numbers are 843, 489, 830, 630

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

Apply this formula for all numbers.

Step1:

LCM(843, 489) = 137409

GCD(843, 489) = ( 843 x 489 ) / 137409

= 843 / 489

= 843

Step2:

LCM(3, 830) = 2490

GCD(3, 830) = ( 3 x 830 ) / 2490

= 3 / 830

= 3

Step3:

LCM(1, 630) = 630

GCD(1, 630) = ( 1 x 630 ) / 630

= 1 / 630

= 1

So, Greatest Common Divisor of 843, 489, 830, 630 is 1
