Given numbers are 717, 743, 390, 342

The list of prime factors of all numbers are

Prime factors of 717 are 3 x 239

Prime factors of 743 are 743

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 342 are 2 x 3 x 3 x 19

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

Given numbers are 717, 743, 390, 342

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

Apply this formula for all numbers.

Step1:

LCM(717, 743) = 532731

GCD(717, 743) = ( 717 x 743 ) / 532731

= 717 / 743

= 717

Step2:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

Step3:

LCM(1, 342) = 342

GCD(1, 342) = ( 1 x 342 ) / 342

= 1 / 342

= 1

So, Greatest Common Divisor of 717, 743, 390, 342 is 1
