Given numbers are 681, 126, 465, 686

The list of prime factors of all numbers are

Prime factors of 681 are 3 x 227

Prime factors of 126 are 2 x 3 x 3 x 7

Prime factors of 465 are 3 x 5 x 31

Prime factors of 686 are 2 x 7 x 7 x 7

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

Given numbers are 681, 126, 465, 686

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

Apply this formula for all numbers.

Step1:

LCM(681, 126) = 28602

GCD(681, 126) = ( 681 x 126 ) / 28602

= 681 / 126

= 681

Step2:

LCM(3, 465) = 465

GCD(3, 465) = ( 3 x 465 ) / 465

= 3 / 465

= 3

Step3:

LCM(3, 686) = 2058

GCD(3, 686) = ( 3 x 686 ) / 2058

= 3 / 686

= 3

So, Greatest Common Divisor of 681, 126, 465, 686 is 1
