Given numbers are 385, 408, 287, 834

The list of prime factors of all numbers are

Prime factors of 385 are 5 x 7 x 11

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

Prime factors of 287 are 7 x 41

Prime factors of 834 are 2 x 3 x 139

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

Given numbers are 385, 408, 287, 834

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

Apply this formula for all numbers.

Step1:

LCM(385, 408) = 157080

GCD(385, 408) = ( 385 x 408 ) / 157080

= 385 / 408

= 385

Step2:

LCM(1, 287) = 287

GCD(1, 287) = ( 1 x 287 ) / 287

= 1 / 287

= 1

Step3:

LCM(1, 834) = 834

GCD(1, 834) = ( 1 x 834 ) / 834

= 1 / 834

= 1

So, Greatest Common Divisor of 385, 408, 287, 834 is 1
