Greatest Common Factor
We found the factors 86,90,392 . The biggest common factor number is the GCF number.
So the greatest common factor 86,90,392 is 2.
Lets's calculate LCM of 18,17,898
2 | 18, 17, 898 |
9, 17, 449 |
∴ So the LCM of the given numbers is 2 x 9 x 17 x 449 = 137394
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/137394
Therefore, the GCF of Fractions 86/18,90/17,392/898 is 2/137394
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 18,17,898 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(18,17,898) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(18,17,898) x common factors =1 x 2 = 2
LCM(18,17,898) = ( 18 × 17 × 898 ) / 2
LCM(18,17,898) = 274788 / 2
LCM(18,17,898) = 137394
