Given numbers are 843, 442, 154, 637

The list of prime factors of all numbers are

Prime factors of 843 are 3 x 281

Prime factors of 442 are 2 x 13 x 17

Prime factors of 154 are 2 x 7 x 11

Prime factors of 637 are 7 x 7 x 13

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

Given numbers are 843, 442, 154, 637

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

Apply this formula for all numbers.

Step1:

LCM(843, 442) = 372606

GCD(843, 442) = ( 843 x 442 ) / 372606

= 843 / 442

= 843

Step2:

LCM(1, 154) = 154

GCD(1, 154) = ( 1 x 154 ) / 154

= 1 / 154

= 1

Step3:

LCM(1, 637) = 637

GCD(1, 637) = ( 1 x 637 ) / 637

= 1 / 637

= 1

So, Greatest Common Divisor of 843, 442, 154, 637 is 1
