Greatest Common Factor
We found the factors 19,88,352 . The biggest common factor number is the GCF number.
So the greatest common factor 19,88,352 is 1.
Lets's calculate LCM of 420,812,720
2 | 420, 812, 720 |
2 | 210, 406, 360 |
3 | 105, 203, 180 |
5 | 35, 203, 60 |
7 | 7, 203, 12 |
1, 29, 12 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 5 x 7 x 1 x 29 x 12 = 146160
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/146160
Therefore, the GCF of Fractions 19/420,88/812,352/720 is 1/146160
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 420,812,720 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(420,812,720) = 4
common factors(in case of two or more numbers have common factors) = 420
GCF(420,812,720) x common factors =4 x 420 = 1680
LCM(420,812,720) = ( 420 × 812 × 720 ) / 1680
LCM(420,812,720) = 245548800 / 1680
LCM(420,812,720) = 146160
