Given numbers are 786, 858, 781, 454

The list of prime factors of all numbers are

Prime factors of 786 are 2 x 3 x 131

Prime factors of 858 are 2 x 3 x 11 x 13

Prime factors of 781 are 11 x 71

Prime factors of 454 are 2 x 227

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

Given numbers are 786, 858, 781, 454

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

Apply this formula for all numbers.

Step1:

LCM(786, 858) = 112398

GCD(786, 858) = ( 786 x 858 ) / 112398

= 786 / 858

= 786

Step2:

LCM(6, 781) = 4686

GCD(6, 781) = ( 6 x 781 ) / 4686

= 6 / 781

= 6

Step3:

LCM(1, 454) = 454

GCD(1, 454) = ( 1 x 454 ) / 454

= 1 / 454

= 1

So, Greatest Common Divisor of 786, 858, 781, 454 is 1
