Given numbers are 781, 315, 681, 905

The list of prime factors of all numbers are

Prime factors of 781 are 11 x 71

Prime factors of 315 are 3 x 3 x 5 x 7

Prime factors of 681 are 3 x 227

Prime factors of 905 are 5 x 181

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

Given numbers are 781, 315, 681, 905

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

Apply this formula for all numbers.

Step1:

LCM(781, 315) = 246015

GCD(781, 315) = ( 781 x 315 ) / 246015

= 781 / 315

= 781

Step2:

LCM(1, 681) = 681

GCD(1, 681) = ( 1 x 681 ) / 681

= 1 / 681

= 1

Step3:

LCM(1, 905) = 905

GCD(1, 905) = ( 1 x 905 ) / 905

= 1 / 905

= 1

So, Greatest Common Divisor of 781, 315, 681, 905 is 1
