Given numbers are 381,146,876,846
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 381,146,876,846 is 15686532.
Find LCM of 381,146,876,846 with Prime Factorization
| 2 | 381, 146, 876, 846 |
| 3 | 381, 73, 438, 423 |
| 73 | 127, 73, 146, 141 |
| 127, 1, 2, 141 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 73 x 127 x 1 x 2 x 141 = 15686532
Therefore, the lowest common multiple of 381,146,876,846 is 15686532.
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.
381 x 146 x 876 x 846 = 41224206096
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.
381 : 1, 3, 127, 381
146 : 1, 2, 73, 146
876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876
846 : 1, 2, 3, 6, 9, 18, 47, 94, 141, 282, 423, 846
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,146,876,846, is 1.
Now, the common factors can be found like this.
381:3x 127
146:2x 73
876:2x 2x 3x 73
846:2x 3x 3x 47
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 3x 3x 73 = 2628
Therefore, the value for common factors is 2628.
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 = 41224206096/(1x2628)
LCM = 41224206096/2628
LCM = 15686532
Thus, we can understand that the LCM of 381,146,876,846 is 15686532.
