Given numbers are 408, 436, 588, 687

The list of prime factors of all numbers are

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

Prime factors of 436 are 2 x 2 x 109

Prime factors of 588 are 2 x 2 x 3 x 7 x 7

Prime factors of 687 are 3 x 229

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

Given numbers are 408, 436, 588, 687

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

Apply this formula for all numbers.

Step1:

LCM(408, 436) = 44472

GCD(408, 436) = ( 408 x 436 ) / 44472

= 408 / 436

= 408

Step2:

LCM(4, 588) = 588

GCD(4, 588) = ( 4 x 588 ) / 588

= 4 / 588

= 4

Step3:

LCM(4, 687) = 2748

GCD(4, 687) = ( 4 x 687 ) / 2748

= 4 / 687

= 4

So, Greatest Common Divisor of 408, 436, 588, 687 is 1
