Given numbers are 129,243,118,981
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 129,243,118,981 is 134395038.
Find LCM of 129,243,118,981 with Prime Factorization
| 3 | 129, 243, 118, 981 |
| 3 | 43, 81, 118, 327 |
| 43, 27, 118, 109 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 43 x 27 x 118 x 109 = 134395038
Therefore, the lowest common multiple of 129,243,118,981 is 134395038.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
129 x 243 x 118 x 981 = 3628666026
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
129 : 1, 3, 43, 129
243 : 1, 3, 9, 27, 81, 243
118 : 1, 2, 59, 118
981 : 1, 3, 9, 109, 327, 981
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 129,243,118,981, is 1.
Now, the common factors can be found like this.
129:3x 43
243:3x 3x 3x 3x 3
118:2x 59
981:3x 3x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3 = 27
Therefore, the value for common factors is 27.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 3628666026/(1x27)
LCM = 3628666026/27
LCM = 134395038
Thus, we can understand that the LCM of 129,243,118,981 is 134395038.
