Given numbers are 687, 260, 429, 455

The list of prime factors of all numbers are

Prime factors of 687 are 3 x 229

Prime factors of 260 are 2 x 2 x 5 x 13

Prime factors of 429 are 3 x 11 x 13

Prime factors of 455 are 5 x 7 x 13

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

Given numbers are 687, 260, 429, 455

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

Apply this formula for all numbers.

Step1:

LCM(687, 260) = 178620

GCD(687, 260) = ( 687 x 260 ) / 178620

= 687 / 260

= 687

Step2:

LCM(1, 429) = 429

GCD(1, 429) = ( 1 x 429 ) / 429

= 1 / 429

= 1

Step3:

LCM(1, 455) = 455

GCD(1, 455) = ( 1 x 455 ) / 455

= 1 / 455

= 1

So, Greatest Common Divisor of 687, 260, 429, 455 is 1
