Given numbers are 345, 731, 572, 123

The list of prime factors of all numbers are

Prime factors of 345 are 3 x 5 x 23

Prime factors of 731 are 17 x 43

Prime factors of 572 are 2 x 2 x 11 x 13

Prime factors of 123 are 3 x 41

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

Given numbers are 345, 731, 572, 123

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

Apply this formula for all numbers.

Step1:

LCM(345, 731) = 252195

GCD(345, 731) = ( 345 x 731 ) / 252195

= 345 / 731

= 345

Step2:

LCM(1, 572) = 572

GCD(1, 572) = ( 1 x 572 ) / 572

= 1 / 572

= 1

Step3:

LCM(1, 123) = 123

GCD(1, 123) = ( 1 x 123 ) / 123

= 1 / 123

= 1

So, Greatest Common Divisor of 345, 731, 572, 123 is 1
