Know Least Common Multiple of fractions 3400/138, 7876/680 quickly i.e. 3347300 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 3400/138, 7876/680 is 3347300.
LCM(3400/138, 7876/680) = 3347300
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 3400/138,7876/680
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 3400,7876
Least Common Multiple of Numerators i.e. LCM of 3400,7876 is 6694600.
GCF of Denominators means GCF of 138,680 as per the given fractions.
GCF of 138,680 is 2 as it is the largest common factor for these numbers.
Lets's calculate LCM of 3400,7876
2 | 3400, 7876 |
2 | 1700, 3938 |
850, 1969 |
∴ So the LCM of the given numbers is 2 x 2 x 850 x 1969 = 6694600
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 3400,7876 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(3400,7876) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(3400,7876) x common factors =4 x 1 = 4
LCM(3400,7876) = ( 3400 × 7876 ) / 4
LCM(3400,7876) = 26778400 / 4
LCM(3400,7876) = 6694600
Lets's calculate GCF of 138,680
2 | 138, 680 |
69, 340 |
∴ So the GCF of the given numbers is 2 = 2
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 6694600/2
Therefore the LCM of Fractions 3400/138,7876/680 is 3347300
