Given numbers are 687, 727, 924, 221

The list of prime factors of all numbers are

Prime factors of 687 are 3 x 229

Prime factors of 727 are 727

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

Prime factors of 221 are 13 x 17

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

Given numbers are 687, 727, 924, 221

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

Apply this formula for all numbers.

Step1:

LCM(687, 727) = 499449

GCD(687, 727) = ( 687 x 727 ) / 499449

= 687 / 727

= 687

Step2:

LCM(1, 924) = 924

GCD(1, 924) = ( 1 x 924 ) / 924

= 1 / 924

= 1

Step3:

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

= 1 / 221

= 1

So, Greatest Common Divisor of 687, 727, 924, 221 is 1
