Therefore, GCD of numbers 679, 860, 489 is 1

Given Input Data is 679, 860, 489

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 679 is 7 x 97

Prime Factorization of 860 is 2 x 2 x 5 x 43

Prime Factorization of 489 is 3 x 163

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

Step1:

Let's calculate the GCD of first two numbers

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

LCM(679, 860) = 583940

GCD(679, 860) = ( 679 x 860 ) / 583940

GCD(679, 860) = 583940 / 583940

GCD(679, 860) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 489

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

LCM(1, 489) = 489

GCD(1, 489) = ( 1 x 489 ) / 489

GCD(1, 489) = 489 / 489

GCD(1, 489) = 1

GCD of 679, 860, 489 is 1
