Given numbers are 385, 427, 408, 805

The list of prime factors of all numbers are

Prime factors of 385 are 5 x 7 x 11

Prime factors of 427 are 7 x 61

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

Prime factors of 805 are 5 x 7 x 23

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

Given numbers are 385, 427, 408, 805

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

Apply this formula for all numbers.

Step1:

LCM(385, 427) = 23485

GCD(385, 427) = ( 385 x 427 ) / 23485

= 385 / 427

= 385

Step2:

LCM(7, 408) = 2856

GCD(7, 408) = ( 7 x 408 ) / 2856

= 7 / 408

= 7

Step3:

LCM(1, 805) = 805

GCD(1, 805) = ( 1 x 805 ) / 805

= 1 / 805

= 1

So, Greatest Common Divisor of 385, 427, 408, 805 is 1
