How to find the Least Common Multiple of 46 and 56?
On this page below, we'll use the Prime Factorisation, and the List of Multiples method to find out the LCM of 46 and 56.
Follow the steps below, and let's calculate the LCM of 46 and 56.
Method 1 - Prime factorization
Step 1: Create a list of all the prime factors of the numbers 46 and 56:
Prime factors of 46
The prime factors of 46 are 2 and 23. Prime factorization of 46 in exponential form is:
46 = 21x231
Prime factors of 56
The prime factors of 56 are 2, 2, 2 and 7. Prime factorization of 56 in exponential form is:
56 = 23x71
Step 2: Identify the highest power of each prime number from the above boxes:
23, 231, 71
Step 3: Multiply these values together:
23x231x71=1288
Step 4: The result:
As seen on the calculation above, we have now obtained the LCM of 46 and 56.
The Least Common Multiple of 46 and 56 is 1288.
Method 2 - List of Multiples
