Know Least Common Multiple of fractions 789/480, 8621/720 quickly i.e. 6801969/240 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 789/480, 8621/720 is 6801969/240.
LCM(789/480, 8621/720) = 6801969/240
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 789/480,8621/720
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 789,8621
Least Common Multiple of Numerators i.e. LCM of 789,8621 is 6801969.
GCF of Denominators means GCF of 480,720 as per the given fractions.
GCF of 480,720 is 240 as it is the largest common factor for these numbers.
Lets's calculate LCM of 789,8621
Given numbers has no common factors except 1. So, there LCM is their product i.e 6801969
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 789,8621 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(789,8621) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(789,8621) x common factors =1 x 1 = 1
LCM(789,8621) = ( 789 × 8621 ) / 1
LCM(789,8621) = 6801969 / 1
LCM(789,8621) = 6801969
Lets's calculate GCF of 480,720
2 | 480, 720 |
2 | 240, 360 |
2 | 120, 180 |
2 | 60, 90 |
3 | 30, 45 |
5 | 10, 15 |
2, 3 |
∴ So the GCF of the given numbers is 2 x 2 x 2 x 2 x 3 x 5 = 240
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 6801969/240
Therefore the LCM of Fractions 789/480,8621/720 is 6801969/240
