Given numbers are 412, 648, 705, 449

The list of prime factors of all numbers are

Prime factors of 412 are 2 x 2 x 103

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 705 are 3 x 5 x 47

Prime factors of 449 are 449

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

Given numbers are 412, 648, 705, 449

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

Apply this formula for all numbers.

Step1:

LCM(412, 648) = 66744

GCD(412, 648) = ( 412 x 648 ) / 66744

= 412 / 648

= 412

Step2:

LCM(4, 705) = 2820

GCD(4, 705) = ( 4 x 705 ) / 2820

= 4 / 705

= 4

Step3:

LCM(1, 449) = 449

GCD(1, 449) = ( 1 x 449 ) / 449

= 1 / 449

= 1

So, Greatest Common Divisor of 412, 648, 705, 449 is 1
