Given numbers are 781, 816, 120, 478

The list of prime factors of all numbers are

Prime factors of 781 are 11 x 71

Prime factors of 816 are 2 x 2 x 2 x 2 x 3 x 17

Prime factors of 120 are 2 x 2 x 2 x 3 x 5

Prime factors of 478 are 2 x 239

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

Given numbers are 781, 816, 120, 478

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

Apply this formula for all numbers.

Step1:

LCM(781, 816) = 637296

GCD(781, 816) = ( 781 x 816 ) / 637296

= 781 / 816

= 781

Step2:

LCM(1, 120) = 120

GCD(1, 120) = ( 1 x 120 ) / 120

= 1 / 120

= 1

Step3:

LCM(1, 478) = 478

GCD(1, 478) = ( 1 x 478 ) / 478

= 1 / 478

= 1

So, Greatest Common Divisor of 781, 816, 120, 478 is 1
