How to find the Least Common Multiple of 53 and 63?
On this page below, we'll use the Prime Factorisation, and the List of Multiples method to find out the LCM of 53 and 63.
Follow the steps below, and let's calculate the LCM of 53 and 63.
Method 1 - Prime factorization
Step 1: Create a list of all the prime factors of the numbers 53 and 63:
Prime factors of 53
The prime factors of 53 are 53. Prime factorization of 53 in exponential form is:
53 = 531
Prime factors of 63
The prime factors of 63 are 3, 3 and 7. Prime factorization of 63 in exponential form is:
63 = 32x71
Step 2: Identify the highest power of each prime number from the above boxes:
531, 32, 71
Step 3: Multiply these values together:
531x32x71=3339
Step 4: The result:
As seen on the calculation above, we have now obtained the LCM of 53 and 63.
The Least Common Multiple of 53 and 63 is 3339.
Method 2 - List of Multiples
