So, the LCM of 69, 76 is 5244.
One method for determining the LCM of 69 and 76 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 69's prime factorization:3 | 69 |
23 | 23 |
1 |
Prime factors of 69 are 3,23.
69 = 31×231
And this is 76's prime factorization:
2 | 76 |
2 | 38 |
19 | 19 |
1 |
Prime factors of 76 are 2,19.
76 = 22×191
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: 3,23, 2,19
.22×31×191×231 = 5244
This shows that the LCM of 69 and 76 is 5244.
The first step in determining the Least Common Multiple of 69 and 76 is to generate a list of multiples for each number.
Lets look at the multiples of these two numbers, 69 and 76:
Lets look at the first ten multiples of these numbers, 69 and 76:
69,138,207,276,345,414,483,552,621,1173 are the first ten multiples of 69.
76,152,228,304,380,456,532,608,684,1292 are the first ten multiples of 76.
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 69 and 76, for example, are 828, 1173, and 1216. 5244 is the least common multiple since it is the smallest.
69 and 76 have an LCM of 5244.
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 69 and 76, than apply into the LCM equation.
GCF(69,76) = 1
LCM(69,76) = ( 69 × 76) / 1
LCM(69,76) = 5244 / 1
LCM(69,76) = 5244
