Given numbers are 385, 364, 147, 687

The list of prime factors of all numbers are

Prime factors of 385 are 5 x 7 x 11

Prime factors of 364 are 2 x 2 x 7 x 13

Prime factors of 147 are 3 x 7 x 7

Prime factors of 687 are 3 x 229

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

Given numbers are 385, 364, 147, 687

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

Apply this formula for all numbers.

Step1:

LCM(385, 364) = 20020

GCD(385, 364) = ( 385 x 364 ) / 20020

= 385 / 364

= 385

Step2:

LCM(7, 147) = 147

GCD(7, 147) = ( 7 x 147 ) / 147

= 7 / 147

= 7

Step3:

LCM(7, 687) = 4809

GCD(7, 687) = ( 7 x 687 ) / 4809

= 7 / 687

= 7

So, Greatest Common Divisor of 385, 364, 147, 687 is 1
