Greatest Common Factor
We found the factors 579,460,813 . The biggest common factor number is the GCF number.
So the greatest common factor 579,460,813 is 1.
Lets's calculate LCM of 51,20,20
2 | 51, 20, 20 |
2 | 51, 10, 10 |
5 | 51, 5, 5 |
51, 1, 1 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 51 x 1 x 1 = 1020
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1020
Therefore, the GCF of Fractions 579/51,460/20,813/20 is 1/1020
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 51,20,20 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(51,20,20) = 1
common factors(in case of two or more numbers have common factors) = 20
GCF(51,20,20) x common factors =1 x 20 = 20
LCM(51,20,20) = ( 51 × 20 × 20 ) / 20
LCM(51,20,20) = 20400 / 20
LCM(51,20,20) = 1020
