Given numbers are 687, 207, 408, 424

The list of prime factors of all numbers are

Prime factors of 687 are 3 x 229

Prime factors of 207 are 3 x 3 x 23

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

Prime factors of 424 are 2 x 2 x 2 x 53

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

Given numbers are 687, 207, 408, 424

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

Apply this formula for all numbers.

Step1:

LCM(687, 207) = 47403

GCD(687, 207) = ( 687 x 207 ) / 47403

= 687 / 207

= 687

Step2:

LCM(3, 408) = 408

GCD(3, 408) = ( 3 x 408 ) / 408

= 3 / 408

= 3

Step3:

LCM(3, 424) = 1272

GCD(3, 424) = ( 3 x 424 ) / 1272

= 3 / 424

= 3

So, Greatest Common Divisor of 687, 207, 408, 424 is 1
