Given numbers are 630, 843, 865

The list of prime factors of all numbers are

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

Prime factors of 843 are 3 x 281

Prime factors of 865 are 5 x 173

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

Given numbers are 630, 843, 865

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

Apply this formula for all numbers.

Step1:

LCM(630, 843) = 177030

GCD(630, 843) = ( 630 x 843 ) / 177030

= 630 / 843

= 630

Step2:

LCM(3, 865) = 2595

GCD(3, 865) = ( 3 x 865 ) / 2595

= 3 / 865

= 3

So, Greatest Common Divisor of 630, 843, 865 is 1
