Know Least Common Multiple of fractions 15/30, 80/25, 960/63 quickly i.e. 960 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 15/30, 80/25, 960/63 is 960.
LCM(15/30, 80/25, 960/63) = 960
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 15/30,80/25,960/63
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 15,80,960
Least Common Multiple of Numerators i.e. LCM of 15,80,960 is 960.
GCF of Denominators means GCF of 30,25,63 as per the given fractions.
GCF of 30,25,63 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 15,80,960
2 | 15, 80, 960 |
2 | 15, 40, 480 |
2 | 15, 20, 240 |
2 | 15, 10, 120 |
3 | 15, 5, 60 |
5 | 5, 5, 20 |
1, 1, 4 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 3 x 5 x 1 x 1 x 4 = 960
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 15,80,960 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(15,80,960) = 5
common factors(in case of two or more numbers have common factors) = 240
GCF(15,80,960) x common factors =5 x 240 = 1200
LCM(15,80,960) = ( 15 × 80 × 960 ) / 1200
LCM(15,80,960) = 1152000 / 1200
LCM(15,80,960) = 960
Lets's calculate GCF of 30,25,63
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 960/1
Therefore the LCM of Fractions 15/30,80/25,960/63 is 960
