Given numbers are 685, 695, 924, 231

The list of prime factors of all numbers are

Prime factors of 685 are 5 x 137

Prime factors of 695 are 5 x 139

Prime factors of 924 are 2 x 2 x 3 x 7 x 11

Prime factors of 231 are 3 x 7 x 11

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

Given numbers are 685, 695, 924, 231

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

Apply this formula for all numbers.

Step1:

LCM(685, 695) = 95215

GCD(685, 695) = ( 685 x 695 ) / 95215

= 685 / 695

= 685

Step2:

LCM(5, 924) = 4620

GCD(5, 924) = ( 5 x 924 ) / 4620

= 5 / 924

= 5

Step3:

LCM(1, 231) = 231

GCD(1, 231) = ( 1 x 231 ) / 231

= 1 / 231

= 1

So, Greatest Common Divisor of 685, 695, 924, 231 is 1
