Know Least Common Multiple of fractions 840/65, 620/62, 279/119 quickly i.e. 78120 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 840/65, 620/62, 279/119 is 78120.
LCM(840/65, 620/62, 279/119) = 78120
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 840/65,620/62,279/119
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 840,620,279
Least Common Multiple of Numerators i.e. LCM of 840,620,279 is 78120.
GCF of Denominators means GCF of 65,62,119 as per the given fractions.
GCF of 65,62,119 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 840,620,279
2 | 840, 620, 279 |
2 | 420, 310, 279 |
3 | 210, 155, 279 |
5 | 70, 155, 93 |
31 | 14, 31, 93 |
14, 1, 3 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 5 x 31 x 14 x 1 x 3 = 78120
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 840,620,279 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(840,620,279) = 1
common factors(in case of two or more numbers have common factors) = 1860
GCF(840,620,279) x common factors =1 x 1860 = 1860
LCM(840,620,279) = ( 840 × 620 × 279 ) / 1860
LCM(840,620,279) = 145303200 / 1860
LCM(840,620,279) = 78120
Lets's calculate GCF of 65,62,119
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 78120/1
Therefore the LCM of Fractions 840/65,620/62,279/119 is 78120
