Least Common Multiple (LCM) of 63 and 71 with the help of Prime Factorisation
One method for determining the LCM of 63 and 71 is to compare the prime factorization of each number. You can find the prime factorization for each number by following the instructions below:
Here is 63's prime factorization:
| 3 | 63 |
| 3 | 21 |
| 7 | 7 |
| 1 |
Prime factors of 63 are 3,7.
63 = 32×71
And this is 71's prime factorization:
| 71 | 71 |
| 1 |
Prime factors of 71 are 71.
71 = 711
When comparing the prime factorization of these two numbers, look for the highest power to which each prime factor is raised. In this case, the following primary factors must be considered: 3,7,71
.32×71×711 = 4473
This shows that the LCM of 63 and 71 is 4473.
How to Calculate the LCM of 63 and 71 Using Common Multiples
The first step in determining the Least Common Multiple of 63 and 71 is to generate a list of multiples for each number.
Lets look at the multiples of these two numbers, 63 and 71:
Lets look at the first ten multiples of these numbers, 63 and 71:
63,126,189,252,315,378,441,504,567,1071 are the first ten multiples of 63.
71,142,213,284,355,426,497,568,639,1207 are the first ten multiples of 71.
You can continue to list the multiples of these numbers until you find a match. Once you have found a match, or several matches, the Least Common Multiple is the smallest of these matches. The first matching multiple(s) of 63 and 71, for example, are 756, 1071, and 1136. 4473 is the least common multiple since it is the smallest.
63 and 71 have an LCM of 4473.
Least Common Multiple of 63 and 71 with GCF Formula
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 63 and 71, than apply into the LCM equation.
GCF(63,71) = 1
LCM(63,71) = ( 63 × 71) / 1
LCM(63,71) = 4473 / 1
LCM(63,71) = 4473
