Know Least Common Multiple of fractions 142/9, 80/70 quickly i.e. 5680 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 142/9, 80/70 is 5680.
LCM(142/9, 80/70) = 5680
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 142/9,80/70
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 142,80
Least Common Multiple of Numerators i.e. LCM of 142,80 is 5680.
GCF of Denominators means GCF of 9,70 as per the given fractions.
GCF of 9,70 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 142,80
2 | 142, 80 |
71, 40 |
∴ So the LCM of the given numbers is 2 x 71 x 40 = 5680
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 142,80 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(142,80) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(142,80) x common factors =2 x 1 = 2
LCM(142,80) = ( 142 × 80 ) / 2
LCM(142,80) = 11360 / 2
LCM(142,80) = 5680
Lets's calculate GCF of 9,70
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 5680/1
Therefore the LCM of Fractions 142/9,80/70 is 5680
