Given numbers are 385, 866, 400, 686

The list of prime factors of all numbers are

Prime factors of 385 are 5 x 7 x 11

Prime factors of 866 are 2 x 433

Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5

Prime factors of 686 are 2 x 7 x 7 x 7

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

Given numbers are 385, 866, 400, 686

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

Apply this formula for all numbers.

Step1:

LCM(385, 866) = 333410

GCD(385, 866) = ( 385 x 866 ) / 333410

= 385 / 866

= 385

Step2:

LCM(1, 400) = 400

GCD(1, 400) = ( 1 x 400 ) / 400

= 1 / 400

= 1

Step3:

LCM(1, 686) = 686

GCD(1, 686) = ( 1 x 686 ) / 686

= 1 / 686

= 1

So, Greatest Common Divisor of 385, 866, 400, 686 is 1
