How to find the Least Common Multiple of 44 and 55?
On this page below, we'll use the Prime Factorisation, and the List of Multiples method to find out the LCM of 44 and 55.
Follow the steps below, and let's calculate the LCM of 44 and 55.
Method 1 - Prime factorization
Step 1: Create a list of all the prime factors of the numbers 44 and 55:
Prime factors of 44
The prime factors of 44 are 2, 2 and 11. Prime factorization of 44 in exponential form is:
44 = 22x111
Prime factors of 55
The prime factors of 55 are 5 and 11. Prime factorization of 55 in exponential form is:
55 = 51x111
Step 2: Identify the highest power of each prime number from the above boxes:
22, 111, 51
Step 3: Multiply these values together:
22x111x51=220
Step 4: The result:
As seen on the calculation above, we have now obtained the LCM of 44 and 55.
The Least Common Multiple of 44 and 55 is 220.
Method 2 - List of Multiples
Find and list multiples of each number until the first common multiple is found. This is the lowest common multiple.
Multiples of 44:
44, 88, 132, 176, 220, 264, 308, 352
Multiples of 55:
55, 110, 165, 220, 275, 330, 385
Therefore,
LCM(44, 55) = 220
