Given numbers are 786, 858, 248, 405

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 248 are 2 x 2 x 2 x 31

Prime factors of 405 are 3 x 3 x 3 x 3 x 5

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

Given numbers are 786, 858, 248, 405

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, 248) = 744

GCD(6, 248) = ( 6 x 248 ) / 744

= 6 / 248

= 6

Step3:

LCM(2, 405) = 810

GCD(2, 405) = ( 2 x 405 ) / 810

= 2 / 405

= 2

So, Greatest Common Divisor of 786, 858, 248, 405 is 1
