Greatest Common Factor
We found the factors 25,346,812 . The biggest common factor number is the GCF number.
So the greatest common factor 25,346,812 is 1.
Lets's calculate LCM of 68,57,138
2 | 68, 57, 138 |
3 | 34, 57, 69 |
34, 19, 23 |
∴ So the LCM of the given numbers is 2 x 3 x 34 x 19 x 23 = 89148
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/89148
Therefore, the GCF of Fractions 25/68,346/57,812/138 is 1/89148
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 68,57,138 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(68,57,138) = 1
common factors(in case of two or more numbers have common factors) = 6
GCF(68,57,138) x common factors =1 x 6 = 6
LCM(68,57,138) = ( 68 × 57 × 138 ) / 6
LCM(68,57,138) = 534888 / 6
LCM(68,57,138) = 89148
