Given numbers are 442, 637, 385, 728

The list of prime factors of all numbers are

Prime factors of 442 are 2 x 13 x 17

Prime factors of 637 are 7 x 7 x 13

Prime factors of 385 are 5 x 7 x 11

Prime factors of 728 are 2 x 2 x 2 x 7 x 13

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

Given numbers are 442, 637, 385, 728

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

Apply this formula for all numbers.

Step1:

LCM(442, 637) = 21658

GCD(442, 637) = ( 442 x 637 ) / 21658

= 442 / 637

= 442

Step2:

LCM(13, 385) = 5005

GCD(13, 385) = ( 13 x 385 ) / 5005

= 13 / 385

= 13

Step3:

LCM(1, 728) = 728

GCD(1, 728) = ( 1 x 728 ) / 728

= 1 / 728

= 1

So, Greatest Common Divisor of 442, 637, 385, 728 is 1
