Given numbers are 287, 681, 31, 454

The list of prime factors of all numbers are

Prime factors of 287 are 7 x 41

Prime factors of 681 are 3 x 227

Prime factors of 31 are 31

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 287, 681, 31, 454

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

Apply this formula for all numbers.

Step1:

LCM(287, 681) = 195447

GCD(287, 681) = ( 287 x 681 ) / 195447

= 287 / 681

= 287

Step2:

LCM(1, 31) = 31

GCD(1, 31) = ( 1 x 31 ) / 31

= 1 / 31

= 1

Step3:

LCM(1, 454) = 454

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

= 1 / 454

= 1

So, Greatest Common Divisor of 287, 681, 31, 454 is 1
