Lets's calculate LCM of 114,665
19 | 114, 665 |
6, 35 |
∴ So the LCM of the given numbers is 19 x 6 x 35 = 3990
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/3990
Therefore, the GCF of Fractions 216/114,628/665 is 4/3990
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 114,665 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(114,665) = 19
common factors(in case of two or more numbers have common factors) = 1
GCF(114,665) x common factors =19 x 1 = 19
LCM(114,665) = ( 114 × 665 ) / 19
LCM(114,665) = 75810 / 19
LCM(114,665) = 3990
