Given numbers are 408, 687, 463, 654

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 687 are 3 x 229

Prime factors of 463 are 463

Prime factors of 654 are 2 x 3 x 109

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

Given numbers are 408, 687, 463, 654

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

Apply this formula for all numbers.

Step1:

LCM(408, 687) = 93432

GCD(408, 687) = ( 408 x 687 ) / 93432

= 408 / 687

= 408

Step2:

LCM(3, 463) = 1389

GCD(3, 463) = ( 3 x 463 ) / 1389

= 3 / 463

= 3

Step3:

LCM(1, 654) = 654

GCD(1, 654) = ( 1 x 654 ) / 654

= 1 / 654

= 1

So, Greatest Common Divisor of 408, 687, 463, 654 is 1
