So the greatest common factor 210,522,380 is 2.
Lets's calculate LCM of 138,630,163
2 | 138, 630, 163 |
3 | 69, 315, 163 |
23, 105, 163 |
∴ So the LCM of the given numbers is 2 x 3 x 23 x 105 x 163 = 2361870
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/2361870
Therefore, the GCF of Fractions 210/138,522/630,380/163 is 2/2361870
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 138,630,163 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(138,630,163) = 1
common factors(in case of two or more numbers have common factors) = 6
GCF(138,630,163) x common factors =1 x 6 = 6
LCM(138,630,163) = ( 138 × 630 × 163 ) / 6
LCM(138,630,163) = 14171220 / 6
LCM(138,630,163) = 2361870
