Know Least Common Multiple of fractions 948/80, 657/20, 211/74 quickly i.e. 21903066 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 948/80, 657/20, 211/74 is 21903066.
LCM(948/80, 657/20, 211/74) = 21903066
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 948/80,657/20,211/74
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 948,657,211
Least Common Multiple of Numerators i.e. LCM of 948,657,211 is 43806132.
GCF of Denominators means GCF of 80,20,74 as per the given fractions.
GCF of 80,20,74 is 2 as it is the largest common factor for these numbers.
Lets's calculate LCM of 948,657,211
3 | 948, 657, 211 |
316, 219, 211 |
∴ So the LCM of the given numbers is 3 x 316 x 219 x 211 = 43806132
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 948,657,211 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(948,657,211) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(948,657,211) x common factors =1 x 3 = 3
LCM(948,657,211) = ( 948 × 657 × 211 ) / 3
LCM(948,657,211) = 131418396 / 3
LCM(948,657,211) = 43806132
Lets's calculate GCF of 80,20,74
2 | 80, 20, 74 |
40, 10, 37 |
∴ So the GCF of the given numbers is 2 = 2
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 43806132/2
Therefore the LCM of Fractions 948/80,657/20,211/74 is 21903066
