Given numbers are 102,442,897
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 102,442,897 is 30498.
Find LCM of 102,442,897 with Prime Factorization
| 2 | 102, 442, 897 |
| 3 | 51, 221, 897 |
| 13 | 17, 221, 299 |
| 17 | 17, 17, 23 |
| 1, 1, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 17 x 1 x 1 x 23 = 30498
Therefore, the lowest common multiple of 102,442,897 is 30498.
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.
102 x 442 x 897 = 40440348
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.
102 : 1, 2, 3, 6, 17, 34, 51, 102
442 : 1, 2, 13, 17, 26, 34, 221, 442
897 : 1, 3, 13, 23, 39, 69, 299, 897
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 102,442,897, is 1.
Now, the common factors can be found like this.
102:2x 3x 17
442:2x 13x 17
897:3x 13x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 13x 17 = 1326
Therefore, the value for common factors is 1326.
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 = 40440348/(1x1326)
LCM = 40440348/1326
LCM = 30498
Thus, we can understand that the LCM of 102,442,897 is 30498.
