Given numbers are 242, 210, 805, 385

The list of prime factors of all numbers are

Prime factors of 242 are 2 x 11 x 11

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

Prime factors of 805 are 5 x 7 x 23

Prime factors of 385 are 5 x 7 x 11

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

Given numbers are 242, 210, 805, 385

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

Apply this formula for all numbers.

Step1:

LCM(242, 210) = 25410

GCD(242, 210) = ( 242 x 210 ) / 25410

= 242 / 210

= 242

Step2:

LCM(2, 805) = 1610

GCD(2, 805) = ( 2 x 805 ) / 1610

= 2 / 805

= 2

Step3:

LCM(1, 385) = 385

GCD(1, 385) = ( 1 x 385 ) / 385

= 1 / 385

= 1

So, Greatest Common Divisor of 242, 210, 805, 385 is 1
