Given numbers are 630, 765, 347, 406

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 765 are 3 x 3 x 5 x 17

Prime factors of 347 are 347

Prime factors of 406 are 2 x 7 x 29

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

Given numbers are 630, 765, 347, 406

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

Apply this formula for all numbers.

Step1:

LCM(630, 765) = 10710

GCD(630, 765) = ( 630 x 765 ) / 10710

= 630 / 765

= 630

Step2:

LCM(45, 347) = 15615

GCD(45, 347) = ( 45 x 347 ) / 15615

= 45 / 347

= 45

Step3:

LCM(1, 406) = 406

GCD(1, 406) = ( 1 x 406 ) / 406

= 1 / 406

= 1

So, Greatest Common Divisor of 630, 765, 347, 406 is 1
