Given numbers are 408, 578, 249, 448

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 578 are 2 x 17 x 17

Prime factors of 249 are 3 x 83

Prime factors of 448 are 2 x 2 x 2 x 2 x 2 x 2 x 7

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

Given numbers are 408, 578, 249, 448

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

Apply this formula for all numbers.

Step1:

LCM(408, 578) = 6936

GCD(408, 578) = ( 408 x 578 ) / 6936

= 408 / 578

= 408

Step2:

LCM(34, 249) = 8466

GCD(34, 249) = ( 34 x 249 ) / 8466

= 34 / 249

= 34

Step3:

LCM(1, 448) = 448

GCD(1, 448) = ( 1 x 448 ) / 448

= 1 / 448

= 1

So, Greatest Common Divisor of 408, 578, 249, 448 is 1
