Given numbers are 388,961,124,158
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 388,961,124,158 is 29456572.
Find LCM of 388,961,124,158 with Prime Factorization
| 2 | 388, 961, 124, 158 |
| 2 | 194, 961, 62, 79 |
| 31 | 97, 961, 31, 79 |
| 97, 1, 31, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 31 x 97 x 1 x 31 x 79 = 29456572
Therefore, the lowest common multiple of 388,961,124,158 is 29456572.
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.
388 x 961 x 124 x 158 = 7305229856
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.
388 : 1, 2, 4, 97, 194, 388
961 : 1, 31, 961
124 : 1, 2, 4, 31, 62, 124
158 : 1, 2, 79, 158
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,961,124,158, is 1.
Now, the common factors can be found like this.
388:2x 2x 97
961:31x 31
124:2x 2x 31
158:2x 79
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 31 = 248
Therefore, the value for common factors is 248.
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 = 7305229856/(1x248)
LCM = 7305229856/248
LCM = 29456572
Thus, we can understand that the LCM of 388,961,124,158 is 29456572.
