Given numbers are 289,751,204,840
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 289,751,204,840 is 182312760.
Find LCM of 289,751,204,840 with Prime Factorization
| 2 | 289, 751, 204, 840 |
| 2 | 289, 751, 102, 420 |
| 3 | 289, 751, 51, 210 |
| 17 | 289, 751, 17, 70 |
| 1, 751, 17, 70 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 17 x 1 x 751 x 17 x 70 = 182312760
Therefore, the lowest common multiple of 289,751,204,840 is 182312760.
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.
289 x 751 x 204 x 840 = 37191803040
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.
289 : 1, 17, 289
751 : 1, 751
204 : 1, 2, 3, 4, 6, 12, 17, 34, 51, 68, 102, 204
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 289,751,204,840, is 1.
Now, the common factors can be found like this.
289:17x 17
751:751
204:2x 2x 3x 17
840:2x 2x 2x 3x 5x 7
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 17 = 204
Therefore, the value for common factors is 204.
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 = 37191803040/(1x204)
LCM = 37191803040/204
LCM = 182312760
Thus, we can understand that the LCM of 289,751,204,840 is 182312760.
