Given numbers are 385, 287, 351, 147

The list of prime factors of all numbers are

Prime factors of 385 are 5 x 7 x 11

Prime factors of 287 are 7 x 41

Prime factors of 351 are 3 x 3 x 3 x 13

Prime factors of 147 are 3 x 7 x 7

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

Given numbers are 385, 287, 351, 147

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

Apply this formula for all numbers.

Step1:

LCM(385, 287) = 15785

GCD(385, 287) = ( 385 x 287 ) / 15785

= 385 / 287

= 385

Step2:

LCM(7, 351) = 2457

GCD(7, 351) = ( 7 x 351 ) / 2457

= 7 / 351

= 7

Step3:

LCM(1, 147) = 147

GCD(1, 147) = ( 1 x 147 ) / 147

= 1 / 147

= 1

So, Greatest Common Divisor of 385, 287, 351, 147 is 1
