Greatest Common Factor
We found the factors 392,301 . The biggest common factor number is the GCF number.
So the greatest common factor 392,301 is 7.
Lets's calculate LCM of 18,6170
2 | 18, 6170 |
9, 3085 |
∴ So the LCM of the given numbers is 2 x 9 x 3085 = 55530
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/55530
Therefore, the GCF of Fractions 392/18,301/6170 is 7/55530
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 18,6170 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(18,6170) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(18,6170) x common factors =2 x 1 = 2
LCM(18,6170) = ( 18 × 6170 ) / 2
LCM(18,6170) = 111060 / 2
LCM(18,6170) = 55530
