Know Least Common Multiple of fractions 120/70, 720/897 quickly i.e. 720 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 120/70, 720/897 is 720.
LCM(120/70, 720/897) = 720
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 120/70,720/897
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 120,720
Least Common Multiple of Numerators i.e. LCM of 120,720 is 720.
GCF of Denominators means GCF of 70,897 as per the given fractions.
GCF of 70,897 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 120,720
2 | 120, 720 |
2 | 60, 360 |
2 | 30, 180 |
3 | 15, 90 |
5 | 5, 30 |
1, 6 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 5 x 1 x 6 = 720
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 120,720 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(120,720) = 120
common factors(in case of two or more numbers have common factors) = 1
GCF(120,720) x common factors =120 x 1 = 120
LCM(120,720) = ( 120 × 720 ) / 120
LCM(120,720) = 86400 / 120
LCM(120,720) = 720
Lets's calculate GCF of 70,897
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 720/1
Therefore the LCM of Fractions 120/70,720/897 is 720
