One method for determining the LCM of 981 and 988 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 981's prime factorization:3 | 981 |
3 | 327 |
109 | 109 |
1 |
Prime factors of 981 are 3,109.
981 = 32×1091
And this is 988's prime factorization:
2 | 988 |
2 | 494 |
13 | 247 |
19 | 19 |
1 |
Prime factors of 988 are 2, 13,19.
988 = 22×131×191
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: 3,109, 2, 13,19
.22×32×131×191×1091 = 969228
This shows that the LCM of 981 and 988 is 969228.
The first step in determining the Least Common Multiple of 981 and 988 is to generate a list of multiples for each number.
Lets look at the multiples of these two numbers, 981 and 988:
Lets look at the first ten multiples of these numbers, 981 and 988:
981,1962,2943,3924,4905,5886,6867,7848,8829,16677 are the first ten multiples of 981.
988,1976,2964,3952,4940,5928,6916,7904,8892,16796 are the first ten multiples of 988.
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 981 and 988, for example, are 11772, 16677, and 15808. 969228 is the least common multiple since it is the smallest.
981 and 988 have an LCM of 969228.
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 981 and 988, than apply into the LCM equation.
GCF(981,988) = 1
LCM(981,988) = ( 981 × 988) / 1
LCM(981,988) = 969228 / 1
LCM(981,988) = 969228
