Know Least Common Multiple of fractions 446/73, 639/91, 813/840 quickly i.e. 77233374 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 446/73, 639/91, 813/840 is 77233374.
LCM(446/73, 639/91, 813/840) = 77233374
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 446/73,639/91,813/840
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 446,639,813
Least Common Multiple of Numerators i.e. LCM of 446,639,813 is 77233374.
GCF of Denominators means GCF of 73,91,840 as per the given fractions.
GCF of 73,91,840 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 446,639,813
3 | 446, 639, 813 |
446, 213, 271 |
∴ So the LCM of the given numbers is 3 x 446 x 213 x 271 = 77233374
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 446,639,813 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(446,639,813) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(446,639,813) x common factors =1 x 3 = 3
LCM(446,639,813) = ( 446 × 639 × 813 ) / 3
LCM(446,639,813) = 231700122 / 3
LCM(446,639,813) = 77233374
Lets's calculate GCF of 73,91,840
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 77233374/1
Therefore the LCM of Fractions 446/73,639/91,813/840 is 77233374
