Know Least Common Multiple of fractions 51/91, 90/41, 86/91, 25/284 quickly i.e. 328950 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 51/91, 90/41, 86/91, 25/284 is 328950.
LCM(51/91, 90/41, 86/91, 25/284) = 328950
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 51/91,90/41,86/91,25/284
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 51,90,86,25
Least Common Multiple of Numerators i.e. LCM of 51,90,86,25 is 328950.
GCF of Denominators means GCF of 91,41,91,284 as per the given fractions.
GCF of 91,41,91,284 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 51,90,86,25
2 | 51, 90, 86, 25 |
3 | 51, 45, 43, 25 |
5 | 17, 15, 43, 25 |
17, 3, 43, 5 |
∴ So the LCM of the given numbers is 2 x 3 x 5 x 17 x 3 x 43 x 5 = 328950
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 51,90,86,25 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(51,90,86,25) = 1
common factors(in case of two or more numbers have common factors) = 30
GCF(51,90,86,25) x common factors =1 x 30 = 30
LCM(51,90,86,25) = ( 51 × 90 × 86 × 25 ) / 30
LCM(51,90,86,25) = 9868500 / 30
LCM(51,90,86,25) = 328950
Lets's calculate GCF of 91,41,91,284
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 328950/1
Therefore the LCM of Fractions 51/91,90/41,86/91,25/284 is 328950
