Given numbers are 815, 408, 208, 487

The list of prime factors of all numbers are

Prime factors of 815 are 5 x 163

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

Prime factors of 208 are 2 x 2 x 2 x 2 x 13

Prime factors of 487 are 487

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

Given numbers are 815, 408, 208, 487

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

Apply this formula for all numbers.

Step1:

LCM(815, 408) = 332520

GCD(815, 408) = ( 815 x 408 ) / 332520

= 815 / 408

= 815

Step2:

LCM(1, 208) = 208

GCD(1, 208) = ( 1 x 208 ) / 208

= 1 / 208

= 1

Step3:

LCM(1, 487) = 487

GCD(1, 487) = ( 1 x 487 ) / 487

= 1 / 487

= 1

So, Greatest Common Divisor of 815, 408, 208, 487 is 1
