Given numbers are 105,845,148,468,442
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 105,845,148,468,442 is 133939260.
Find LCM of 105,845,148,468,442 with Prime Factorization
| 2 | 105, 845, 148, 468, 442 |
| 2 | 105, 845, 74, 234, 221 |
| 3 | 105, 845, 37, 117, 221 |
| 5 | 35, 845, 37, 39, 221 |
| 13 | 7, 169, 37, 39, 221 |
| 7, 13, 37, 3, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 13 x 7 x 13 x 37 x 3 x 17 = 133939260
Therefore, the lowest common multiple of 105,845,148,468,442 is 133939260.
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.
105 x 845 x 148 x 468 x 442 = 2716288192800
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.
105 : 1, 3, 5, 7, 15, 21, 35, 105
845 : 1, 5, 13, 65, 169, 845
148 : 1, 2, 4, 37, 74, 148
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
442 : 1, 2, 13, 17, 26, 34, 221, 442
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 105,845,148,468,442, is 1.
Now, the common factors can be found like this.
105:3x 5x 7
845:5x 13x 13
148:2x 2x 37
468:2x 2x 3x 3x 13
442:2x 13x 17
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 3x 5x 13x 13 = 20280
Therefore, the value for common factors is 20280.
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 = 2716288192800/(1x20280)
LCM = 2716288192800/20280
LCM = 133939260
Thus, we can understand that the LCM of 105,845,148,468,442 is 133939260.
