Know Least Common Multiple of fractions 1991/551, 1445/3426 quickly i.e. 2876995 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 1991/551, 1445/3426 is 2876995.
LCM(1991/551, 1445/3426) = 2876995
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 1991/551,1445/3426
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 1991,1445
Least Common Multiple of Numerators i.e. LCM of 1991,1445 is 2876995.
GCF of Denominators means GCF of 551,3426 as per the given fractions.
GCF of 551,3426 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 1991,1445
Given numbers has no common factors except 1. So, there LCM is their product i.e 2876995
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 1991,1445 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(1991,1445) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(1991,1445) x common factors =1 x 1 = 1
LCM(1991,1445) = ( 1991 × 1445 ) / 1
LCM(1991,1445) = 2876995 / 1
LCM(1991,1445) = 2876995
Lets's calculate GCF of 551,3426
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 2876995/1
Therefore the LCM of Fractions 1991/551,1445/3426 is 2876995
