Know Least Common Multiple of fractions 80/87, 87/90, 678/148 quickly i.e. 786480 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 80/87, 87/90, 678/148 is 786480.
LCM(80/87, 87/90, 678/148) = 786480
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 80/87,87/90,678/148
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 80,87,678
Least Common Multiple of Numerators i.e. LCM of 80,87,678 is 786480.
GCF of Denominators means GCF of 87,90,148 as per the given fractions.
GCF of 87,90,148 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 80,87,678
2 | 80, 87, 678 |
3 | 40, 87, 339 |
40, 29, 113 |
∴ So the LCM of the given numbers is 2 x 3 x 40 x 29 x 113 = 786480
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 80,87,678 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(80,87,678) = 1
common factors(in case of two or more numbers have common factors) = 6
GCF(80,87,678) x common factors =1 x 6 = 6
LCM(80,87,678) = ( 80 × 87 × 678 ) / 6
LCM(80,87,678) = 4718880 / 6
LCM(80,87,678) = 786480
Lets's calculate GCF of 87,90,148
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 786480/1
Therefore the LCM of Fractions 80/87,87/90,678/148 is 786480
