Given numbers are 840, 687, 227, 743

The list of prime factors of all numbers are

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

Prime factors of 687 are 3 x 229

Prime factors of 227 are 227

Prime factors of 743 are 743

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

Given numbers are 840, 687, 227, 743

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

Apply this formula for all numbers.

Step1:

LCM(840, 687) = 192360

GCD(840, 687) = ( 840 x 687 ) / 192360

= 840 / 687

= 840

Step2:

LCM(3, 227) = 681

GCD(3, 227) = ( 3 x 227 ) / 681

= 3 / 227

= 3

Step3:

LCM(1, 743) = 743

GCD(1, 743) = ( 1 x 743 ) / 743

= 1 / 743

= 1

So, Greatest Common Divisor of 840, 687, 227, 743 is 1
