Greatest Common Factor
We found the factors 720,930 . The biggest common factor number is the GCF number.
So the greatest common factor 720,930 is 30.
Lets's calculate LCM of 66,898
2 | 66, 898 |
33, 449 |
∴ So the LCM of the given numbers is 2 x 33 x 449 = 29634
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 30/29634
Therefore, the GCF of Fractions 720/66,930/898 is 30/29634
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 66,898 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(66,898) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(66,898) x common factors =2 x 1 = 2
LCM(66,898) = ( 66 × 898 ) / 2
LCM(66,898) = 59268 / 2
LCM(66,898) = 29634
