Know Least Common Multiple of fractions 25/98, 115/28, 450/525 quickly i.e. 10350/7 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 25/98, 115/28, 450/525 is 10350/7.
LCM(25/98, 115/28, 450/525) = 10350/7
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 25/98,115/28,450/525
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 25,115,450
Least Common Multiple of Numerators i.e. LCM of 25,115,450 is 10350.
GCF of Denominators means GCF of 98,28,525 as per the given fractions.
GCF of 98,28,525 is 7 as it is the largest common factor for these numbers.
Lets's calculate LCM of 25,115,450
5 | 25, 115, 450 |
5 | 5, 23, 90 |
1, 23, 18 |
∴ So the LCM of the given numbers is 5 x 5 x 1 x 23 x 18 = 10350
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 25,115,450 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(25,115,450) = 5
common factors(in case of two or more numbers have common factors) = 25
GCF(25,115,450) x common factors =5 x 25 = 125
LCM(25,115,450) = ( 25 × 115 × 450 ) / 125
LCM(25,115,450) = 1293750 / 125
LCM(25,115,450) = 10350
Lets's calculate GCF of 98,28,525
7 | 98, 28, 525 |
14, 4, 75 |
∴ So the GCF of the given numbers is 7 = 7
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 10350/7
Therefore the LCM of Fractions 25/98,115/28,450/525 is 10350/7
