Given numbers are 385, 210, 905, 261

The list of prime factors of all numbers are

Prime factors of 385 are 5 x 7 x 11

Prime factors of 210 are 2 x 3 x 5 x 7

Prime factors of 905 are 5 x 181

Prime factors of 261 are 3 x 3 x 29

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

Given numbers are 385, 210, 905, 261

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

Apply this formula for all numbers.

Step1:

LCM(385, 210) = 2310

GCD(385, 210) = ( 385 x 210 ) / 2310

= 385 / 210

= 385

Step2:

LCM(35, 905) = 6335

GCD(35, 905) = ( 35 x 905 ) / 6335

= 35 / 905

= 35

Step3:

LCM(5, 261) = 1305

GCD(5, 261) = ( 5 x 261 ) / 1305

= 5 / 261

= 5

So, Greatest Common Divisor of 385, 210, 905, 261 is 1
