Given numbers are 687, 808, 570, 411

The list of prime factors of all numbers are

Prime factors of 687 are 3 x 229

Prime factors of 808 are 2 x 2 x 2 x 101

Prime factors of 570 are 2 x 3 x 5 x 19

Prime factors of 411 are 3 x 137

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

Given numbers are 687, 808, 570, 411

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

Apply this formula for all numbers.

Step1:

LCM(687, 808) = 555096

GCD(687, 808) = ( 687 x 808 ) / 555096

= 687 / 808

= 687

Step2:

LCM(1, 570) = 570

GCD(1, 570) = ( 1 x 570 ) / 570

= 1 / 570

= 1

Step3:

LCM(1, 411) = 411

GCD(1, 411) = ( 1 x 411 ) / 411

= 1 / 411

= 1

So, Greatest Common Divisor of 687, 808, 570, 411 is 1
