Given numbers are 345, 815, 714, 252

The list of prime factors of all numbers are

Prime factors of 345 are 3 x 5 x 23

Prime factors of 815 are 5 x 163

Prime factors of 714 are 2 x 3 x 7 x 17

Prime factors of 252 are 2 x 2 x 3 x 3 x 7

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

Given numbers are 345, 815, 714, 252

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

Apply this formula for all numbers.

Step1:

LCM(345, 815) = 56235

GCD(345, 815) = ( 345 x 815 ) / 56235

= 345 / 815

= 345

Step2:

LCM(5, 714) = 3570

GCD(5, 714) = ( 5 x 714 ) / 3570

= 5 / 714

= 5

Step3:

LCM(1, 252) = 252

GCD(1, 252) = ( 1 x 252 ) / 252

= 1 / 252

= 1

So, Greatest Common Divisor of 345, 815, 714, 252 is 1
