Know Least Common Multiple of fractions 780/540, 2279/220 quickly i.e. 88881 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 780/540, 2279/220 is 88881.
LCM(780/540, 2279/220) = 88881
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 780/540,2279/220
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 780,2279
Least Common Multiple of Numerators i.e. LCM of 780,2279 is 1777620.
GCF of Denominators means GCF of 540,220 as per the given fractions.
GCF of 540,220 is 20 as it is the largest common factor for these numbers.
Lets's calculate LCM of 780,2279
Given numbers has no common factors except 1. So, there LCM is their product i.e 1777620
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 780,2279 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(780,2279) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(780,2279) x common factors =1 x 1 = 1
LCM(780,2279) = ( 780 × 2279 ) / 1
LCM(780,2279) = 1777620 / 1
LCM(780,2279) = 1777620
Lets's calculate GCF of 540,220
2 | 540, 220 |
2 | 270, 110 |
5 | 135, 55 |
27, 11 |
∴ So the GCF of the given numbers is 2 x 2 x 5 = 20
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1777620/20
Therefore the LCM of Fractions 780/540,2279/220 is 88881
