Given numbers are 631, 427, 731, 840

The list of prime factors of all numbers are

Prime factors of 631 are 631

Prime factors of 427 are 7 x 61

Prime factors of 731 are 17 x 43

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

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

Given numbers are 631, 427, 731, 840

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

Apply this formula for all numbers.

Step1:

LCM(631, 427) = 269437

GCD(631, 427) = ( 631 x 427 ) / 269437

= 631 / 427

= 631

Step2:

LCM(1, 731) = 731

GCD(1, 731) = ( 1 x 731 ) / 731

= 1 / 731

= 1

Step3:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

So, Greatest Common Divisor of 631, 427, 731, 840 is 1
