Given numbers are 781, 840, 747, 703

The list of prime factors of all numbers are

Prime factors of 781 are 11 x 71

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

Prime factors of 747 are 3 x 3 x 83

Prime factors of 703 are 19 x 37

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

Given numbers are 781, 840, 747, 703

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

Apply this formula for all numbers.

Step1:

LCM(781, 840) = 656040

GCD(781, 840) = ( 781 x 840 ) / 656040

= 781 / 840

= 781

Step2:

LCM(1, 747) = 747

GCD(1, 747) = ( 1 x 747 ) / 747

= 1 / 747

= 1

Step3:

LCM(1, 703) = 703

GCD(1, 703) = ( 1 x 703 ) / 703

= 1 / 703

= 1

So, Greatest Common Divisor of 781, 840, 747, 703 is 1
