Given numbers are 198, 280, 447, 578

The list of prime factors of all numbers are

Prime factors of 198 are 2 x 3 x 3 x 11

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 447 are 3 x 149

Prime factors of 578 are 2 x 17 x 17

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

Given numbers are 198, 280, 447, 578

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

Apply this formula for all numbers.

Step1:

LCM(198, 280) = 27720

GCD(198, 280) = ( 198 x 280 ) / 27720

= 198 / 280

= 198

Step2:

LCM(2, 447) = 894

GCD(2, 447) = ( 2 x 447 ) / 894

= 2 / 447

= 2

Step3:

LCM(1, 578) = 578

GCD(1, 578) = ( 1 x 578 ) / 578

= 1 / 578

= 1

So, Greatest Common Divisor of 198, 280, 447, 578 is 1
