Given numbers are 391, 521, 416, 681

The list of prime factors of all numbers are

Prime factors of 391 are 17 x 23

Prime factors of 521 are 521

Prime factors of 416 are 2 x 2 x 2 x 2 x 2 x 13

Prime factors of 681 are 3 x 227

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

Given numbers are 391, 521, 416, 681

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

Apply this formula for all numbers.

Step1:

LCM(391, 521) = 203711

GCD(391, 521) = ( 391 x 521 ) / 203711

= 391 / 521

= 391

Step2:

LCM(1, 416) = 416

GCD(1, 416) = ( 1 x 416 ) / 416

= 1 / 416

= 1

Step3:

LCM(1, 681) = 681

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

= 1 / 681

= 1

So, Greatest Common Divisor of 391, 521, 416, 681 is 1
