Given numbers are 630, 430, 243, 665

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 430 are 2 x 5 x 43

Prime factors of 243 are 3 x 3 x 3 x 3 x 3

Prime factors of 665 are 5 x 7 x 19

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

Given numbers are 630, 430, 243, 665

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

Apply this formula for all numbers.

Step1:

LCM(630, 430) = 27090

GCD(630, 430) = ( 630 x 430 ) / 27090

= 630 / 430

= 630

Step2:

LCM(10, 243) = 2430

GCD(10, 243) = ( 10 x 243 ) / 2430

= 10 / 243

= 10

Step3:

LCM(1, 665) = 665

GCD(1, 665) = ( 1 x 665 ) / 665

= 1 / 665

= 1

So, Greatest Common Divisor of 630, 430, 243, 665 is 1
