Lets's calculate LCM of 370,3930
2 | 370, 3930 |
5 | 185, 1965 |
37, 393 |
∴ So the LCM of the given numbers is 2 x 5 x 37 x 393 = 145410
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/145410
Therefore, the GCF of Fractions 12/370,7291/3930 is 1/145410
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 370,3930 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(370,3930) = 10
common factors(in case of two or more numbers have common factors) = 1
GCF(370,3930) x common factors =10 x 1 = 10
LCM(370,3930) = ( 370 × 3930 ) / 10
LCM(370,3930) = 1454100 / 10
LCM(370,3930) = 145410
