Given numbers are 785, 778, 560, 717

The list of prime factors of all numbers are

Prime factors of 785 are 5 x 157

Prime factors of 778 are 2 x 389

Prime factors of 560 are 2 x 2 x 2 x 2 x 5 x 7

Prime factors of 717 are 3 x 239

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

Given numbers are 785, 778, 560, 717

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

Apply this formula for all numbers.

Step1:

LCM(785, 778) = 610730

GCD(785, 778) = ( 785 x 778 ) / 610730

= 785 / 778

= 785

Step2:

LCM(1, 560) = 560

GCD(1, 560) = ( 1 x 560 ) / 560

= 1 / 560

= 1

Step3:

LCM(1, 717) = 717

GCD(1, 717) = ( 1 x 717 ) / 717

= 1 / 717

= 1

So, Greatest Common Divisor of 785, 778, 560, 717 is 1
