Greatest Common Factor
We found the factors 98,63,490 . The biggest common factor number is the GCF number.
So the greatest common factor 98,63,490 is 7.
Lets's calculate LCM of 19,48,338
2 | 19, 48, 338 |
19, 24, 169 |
∴ So the LCM of the given numbers is 2 x 19 x 24 x 169 = 154128
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/154128
Therefore, the GCF of Fractions 98/19,63/48,490/338 is 7/154128
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 19,48,338 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(19,48,338) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(19,48,338) x common factors =1 x 2 = 2
LCM(19,48,338) = ( 19 × 48 × 338 ) / 2
LCM(19,48,338) = 308256 / 2
LCM(19,48,338) = 154128
