So the greatest common factor 812,693 is 7.
Lets's calculate LCM of 370,135
5 | 370, 135 |
74, 27 |
∴ So the LCM of the given numbers is 5 x 74 x 27 = 9990
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/9990
Therefore, the GCF of Fractions 812/370,693/135 is 7/9990
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 370,135 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(370,135) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(370,135) x common factors =5 x 1 = 5
LCM(370,135) = ( 370 × 135 ) / 5
LCM(370,135) = 49950 / 5
LCM(370,135) = 9990
