Given numbers are 240, 778, 642, 717

The list of prime factors of all numbers are

Prime factors of 240 are 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 778 are 2 x 389

Prime factors of 642 are 2 x 3 x 107

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 240, 778, 642, 717

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

Apply this formula for all numbers.

Step1:

LCM(240, 778) = 93360

GCD(240, 778) = ( 240 x 778 ) / 93360

= 240 / 778

= 240

Step2:

LCM(2, 642) = 642

GCD(2, 642) = ( 2 x 642 ) / 642

= 2 / 642

= 2

Step3:

LCM(2, 717) = 1434

GCD(2, 717) = ( 2 x 717 ) / 1434

= 2 / 717

= 2

So, Greatest Common Divisor of 240, 778, 642, 717 is 1
