Know Least Common Multiple of fractions 68/75, 45/78, 967/81 quickly i.e. 986340 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 68/75, 45/78, 967/81 is 986340.
LCM(68/75, 45/78, 967/81) = 986340
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 68/75,45/78,967/81
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 68,45,967
Least Common Multiple of Numerators i.e. LCM of 68,45,967 is 2959020.
GCF of Denominators means GCF of 75,78,81 as per the given fractions.
GCF of 75,78,81 is 3 as it is the largest common factor for these numbers.
Lets's calculate LCM of 68,45,967
Given numbers has no common factors except 1. So, there LCM is their product i.e 2959020
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 68,45,967 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(68,45,967) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(68,45,967) x common factors =1 x 1 = 1
LCM(68,45,967) = ( 68 × 45 × 967 ) / 1
LCM(68,45,967) = 2959020 / 1
LCM(68,45,967) = 2959020
Lets's calculate GCF of 75,78,81
3 | 75, 78, 81 |
25, 26, 27 |
∴ So the GCF of the given numbers is 3 = 3
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 2959020/3
Therefore the LCM of Fractions 68/75,45/78,967/81 is 986340
