Given numbers are 715, 663, 717, 840

The list of prime factors of all numbers are

Prime factors of 715 are 5 x 11 x 13

Prime factors of 663 are 3 x 13 x 17

Prime factors of 717 are 3 x 239

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

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

Given numbers are 715, 663, 717, 840

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

Apply this formula for all numbers.

Step1:

LCM(715, 663) = 36465

GCD(715, 663) = ( 715 x 663 ) / 36465

= 715 / 663

= 715

Step2:

LCM(13, 717) = 9321

GCD(13, 717) = ( 13 x 717 ) / 9321

= 13 / 717

= 13

Step3:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

So, Greatest Common Divisor of 715, 663, 717, 840 is 1
