Given numbers are 385, 215, 398, 426

The list of prime factors of all numbers are

Prime factors of 385 are 5 x 7 x 11

Prime factors of 215 are 5 x 43

Prime factors of 398 are 2 x 199

Prime factors of 426 are 2 x 3 x 71

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

Given numbers are 385, 215, 398, 426

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

Apply this formula for all numbers.

Step1:

LCM(385, 215) = 16555

GCD(385, 215) = ( 385 x 215 ) / 16555

= 385 / 215

= 385

Step2:

LCM(5, 398) = 1990

GCD(5, 398) = ( 5 x 398 ) / 1990

= 5 / 398

= 5

Step3:

LCM(1, 426) = 426

GCD(1, 426) = ( 1 x 426 ) / 426

= 1 / 426

= 1

So, Greatest Common Divisor of 385, 215, 398, 426 is 1
