Know Least Common Multiple of fractions 79/820, 391/847, 978/649 quickly i.e. 30209442 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 79/820, 391/847, 978/649 is 30209442.
LCM(79/820, 391/847, 978/649) = 30209442
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 79/820,391/847,978/649
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 79,391,978
Least Common Multiple of Numerators i.e. LCM of 79,391,978 is 30209442.
GCF of Denominators means GCF of 820,847,649 as per the given fractions.
GCF of 820,847,649 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 79,391,978
Given numbers has no common factors except 1. So, there LCM is their product i.e 30209442
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 79,391,978 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(79,391,978) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(79,391,978) x common factors =1 x 1 = 1
LCM(79,391,978) = ( 79 × 391 × 978 ) / 1
LCM(79,391,978) = 30209442 / 1
LCM(79,391,978) = 30209442
Lets's calculate GCF of 820,847,649
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 30209442/1
Therefore the LCM of Fractions 79/820,391/847,978/649 is 30209442
