Given numbers are 842, 994, 420, 743

The list of prime factors of all numbers are

Prime factors of 842 are 2 x 421

Prime factors of 994 are 2 x 7 x 71

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 743 are 743

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

Given numbers are 842, 994, 420, 743

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

Apply this formula for all numbers.

Step1:

LCM(842, 994) = 418474

GCD(842, 994) = ( 842 x 994 ) / 418474

= 842 / 994

= 842

Step2:

LCM(2, 420) = 420

GCD(2, 420) = ( 2 x 420 ) / 420

= 2 / 420

= 2

Step3:

LCM(2, 743) = 1486

GCD(2, 743) = ( 2 x 743 ) / 1486

= 2 / 743

= 2

So, Greatest Common Divisor of 842, 994, 420, 743 is 1
