Know Least Common Multiple of fractions 140/350, 931/217, 687/180 quickly i.e. 12791940 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 140/350, 931/217, 687/180 is 12791940.
LCM(140/350, 931/217, 687/180) = 12791940
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 140/350,931/217,687/180
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 140,931,687
Least Common Multiple of Numerators i.e. LCM of 140,931,687 is 12791940.
GCF of Denominators means GCF of 350,217,180 as per the given fractions.
GCF of 350,217,180 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 140,931,687
7 | 140, 931, 687 |
20, 133, 687 |
∴ So the LCM of the given numbers is 7 x 20 x 133 x 687 = 12791940
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 140,931,687 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(140,931,687) = 1
common factors(in case of two or more numbers have common factors) = 7
GCF(140,931,687) x common factors =1 x 7 = 7
LCM(140,931,687) = ( 140 × 931 × 687 ) / 7
LCM(140,931,687) = 89543580 / 7
LCM(140,931,687) = 12791940
Lets's calculate GCF of 350,217,180
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 12791940/1
Therefore the LCM of Fractions 140/350,931/217,687/180 is 12791940
