Given numbers are 842, 638, 385, 460

The list of prime factors of all numbers are

Prime factors of 842 are 2 x 421

Prime factors of 638 are 2 x 11 x 29

Prime factors of 385 are 5 x 7 x 11

Prime factors of 460 are 2 x 2 x 5 x 23

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

Given numbers are 842, 638, 385, 460

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

Apply this formula for all numbers.

Step1:

LCM(842, 638) = 268598

GCD(842, 638) = ( 842 x 638 ) / 268598

= 842 / 638

= 842

Step2:

LCM(2, 385) = 770

GCD(2, 385) = ( 2 x 385 ) / 770

= 2 / 385

= 2

Step3:

LCM(1, 460) = 460

GCD(1, 460) = ( 1 x 460 ) / 460

= 1 / 460

= 1

So, Greatest Common Divisor of 842, 638, 385, 460 is 1
