Know Least Common Multiple of fractions 7874/387, 1966/688 quickly i.e. 7740142/43 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 7874/387, 1966/688 is 7740142/43.
LCM(7874/387, 1966/688) = 7740142/43
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 7874/387,1966/688
Formula to find LCM of Fractions is
LCM = LCM of Numerators/GCF of Denominators
As per the formula LCM of Fractions let’s split into two parts and find the LCM of Numerators and GCF of Denominators
In the given fractions LCM of Numerators means LCM of 7874,1966
Least Common Multiple of Numerators i.e. LCM of 7874,1966 is 7740142.
GCF of Denominators means GCF of 387,688 as per the given fractions.
GCF of 387,688 is 43 as it is the largest common factor for these numbers.
Lets's calculate LCM of 7874,1966
2 | 7874, 1966 |
3937, 983 |
∴ So the LCM of the given numbers is 2 x 3937 x 983 = 7740142
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 7874,1966 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(7874,1966) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(7874,1966) x common factors =2 x 1 = 2
LCM(7874,1966) = ( 7874 × 1966 ) / 2
LCM(7874,1966) = 15480284 / 2
LCM(7874,1966) = 7740142
Lets's calculate GCF of 387,688
43 | 387, 688 |
9, 16 |
∴ So the GCF of the given numbers is 43 = 43
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 7740142/43
Therefore the LCM of Fractions 7874/387,1966/688 is 7740142/43
