Know Least Common Multiple of fractions 73/42, 78/65, 58/31, 58/550 quickly i.e. 165126 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 73/42, 78/65, 58/31, 58/550 is 165126.
LCM(73/42, 78/65, 58/31, 58/550) = 165126
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 73/42,78/65,58/31,58/550
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 73,78,58,58
Least Common Multiple of Numerators i.e. LCM of 73,78,58,58 is 165126.
GCF of Denominators means GCF of 42,65,31,550 as per the given fractions.
GCF of 42,65,31,550 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 73,78,58,58
2 | 73, 78, 58, 58 |
29 | 73, 39, 29, 29 |
73, 39, 1, 1 |
∴ So the LCM of the given numbers is 2 x 29 x 73 x 39 x 1 x 1 = 165126
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 73,78,58,58 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(73,78,58,58) = 1
common factors(in case of two or more numbers have common factors) = 116
GCF(73,78,58,58) x common factors =1 x 116 = 116
LCM(73,78,58,58) = ( 73 × 78 × 58 × 58 ) / 116
LCM(73,78,58,58) = 19154616 / 116
LCM(73,78,58,58) = 165126
Lets's calculate GCF of 42,65,31,550
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 165126/1
Therefore the LCM of Fractions 73/42,78/65,58/31,58/550 is 165126
