Know Least Common Multiple of fractions 161/65, 892/82, 804/921 quickly i.e. 28866012 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 161/65, 892/82, 804/921 is 28866012.
LCM(161/65, 892/82, 804/921) = 28866012
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 161/65,892/82,804/921
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 161,892,804
Least Common Multiple of Numerators i.e. LCM of 161,892,804 is 28866012.
GCF of Denominators means GCF of 65,82,921 as per the given fractions.
GCF of 65,82,921 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 161,892,804
2 | 161, 892, 804 |
2 | 161, 446, 402 |
161, 223, 201 |
∴ So the LCM of the given numbers is 2 x 2 x 161 x 223 x 201 = 28866012
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 161,892,804 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(161,892,804) = 1
common factors(in case of two or more numbers have common factors) = 4
GCF(161,892,804) x common factors =1 x 4 = 4
LCM(161,892,804) = ( 161 × 892 × 804 ) / 4
LCM(161,892,804) = 115464048 / 4
LCM(161,892,804) = 28866012
Lets's calculate GCF of 65,82,921
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 28866012/1
Therefore the LCM of Fractions 161/65,892/82,804/921 is 28866012
