Lets's calculate LCM of 630,399,478
2 | 630, 399, 478 |
3 | 315, 399, 239 |
7 | 105, 133, 239 |
15, 19, 239 |
∴ So the LCM of the given numbers is 2 x 3 x 7 x 15 x 19 x 239 = 2860830
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2860830
Therefore, the GCF of Fractions 154/630,234/399,985/478 is 1/2860830
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 630,399,478 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(630,399,478) = 1
common factors(in case of two or more numbers have common factors) = 42
GCF(630,399,478) x common factors =1 x 42 = 42
LCM(630,399,478) = ( 630 × 399 × 478 ) / 42
LCM(630,399,478) = 120154860 / 42
LCM(630,399,478) = 2860830
