1,2,3,6,41,82,123,246
Greatest Common Factor
We found the factors 45,278,246 . The biggest common factor number is the GCF number.
So the greatest common factor 45,278,246 is 1.
Lets's calculate LCM of 247,143,931
13 | 247, 143, 931 |
19 | 19, 11, 931 |
1, 11, 49 |
∴ So the LCM of the given numbers is 13 x 19 x 1 x 11 x 49 = 133133
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/133133
Therefore, the GCF of Fractions 45/247,278/143,246/931 is 1/133133
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 247,143,931 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(247,143,931) = 1
common factors(in case of two or more numbers have common factors) = 247
GCF(247,143,931) x common factors =1 x 247 = 247
LCM(247,143,931) = ( 247 × 143 × 931 ) / 247
LCM(247,143,931) = 32883851 / 247
LCM(247,143,931) = 133133
