Greatest Common Factor
We found the factors 71,872,143 . The biggest common factor number is the GCF number.
So the greatest common factor 71,872,143 is 1.
Lets's calculate LCM of 22,86,928
2 | 22, 86, 928 |
11, 43, 464 |
∴ So the LCM of the given numbers is 2 x 11 x 43 x 464 = 438944
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/438944
Therefore, the GCF of Fractions 71/22,872/86,143/928 is 1/438944
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 22,86,928 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(22,86,928) = 2
common factors(in case of two or more numbers have common factors) = 2
GCF(22,86,928) x common factors =2 x 2 = 4
LCM(22,86,928) = ( 22 × 86 × 928 ) / 4
LCM(22,86,928) = 1755776 / 4
LCM(22,86,928) = 438944
