Given numbers are 781, 532, 560, 687

The list of prime factors of all numbers are

Prime factors of 781 are 11 x 71

Prime factors of 532 are 2 x 2 x 7 x 19

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

Prime factors of 687 are 3 x 229

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

Given numbers are 781, 532, 560, 687

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

Apply this formula for all numbers.

Step1:

LCM(781, 532) = 415492

GCD(781, 532) = ( 781 x 532 ) / 415492

= 781 / 532

= 781

Step2:

LCM(1, 560) = 560

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

= 1 / 560

= 1

Step3:

LCM(1, 687) = 687

GCD(1, 687) = ( 1 x 687 ) / 687

= 1 / 687

= 1

So, Greatest Common Divisor of 781, 532, 560, 687 is 1
