Lets's calculate LCM of 74,1786
2 | 74, 1786 |
37, 893 |
∴ So the LCM of the given numbers is 2 x 37 x 893 = 66082
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 11/66082
Therefore, the GCF of Fractions 649/74,946/1786 is 11/66082
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 74,1786 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(74,1786) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(74,1786) x common factors =2 x 1 = 2
LCM(74,1786) = ( 74 × 1786 ) / 2
LCM(74,1786) = 132164 / 2
LCM(74,1786) = 66082
