Given numbers are 345, 630, 751, 231

The list of prime factors of all numbers are

Prime factors of 345 are 3 x 5 x 23

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

Prime factors of 751 are 751

Prime factors of 231 are 3 x 7 x 11

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

Given numbers are 345, 630, 751, 231

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

Apply this formula for all numbers.

Step1:

LCM(345, 630) = 14490

GCD(345, 630) = ( 345 x 630 ) / 14490

= 345 / 630

= 345

Step2:

LCM(15, 751) = 11265

GCD(15, 751) = ( 15 x 751 ) / 11265

= 15 / 751

= 15

Step3:

LCM(1, 231) = 231

GCD(1, 231) = ( 1 x 231 ) / 231

= 1 / 231

= 1

So, Greatest Common Divisor of 345, 630, 751, 231 is 1
