Given numbers are 381,944,801,290
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 381,944,801,290 is 13924391760.
Find LCM of 381,944,801,290 with Prime Factorization
| 2 | 381, 944, 801, 290 |
| 3 | 381, 472, 801, 145 |
| 127, 472, 267, 145 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 127 x 472 x 267 x 145 = 13924391760
Therefore, the lowest common multiple of 381,944,801,290 is 13924391760.
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 944 x 801 x 290 = 83546350560
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
944 : 1, 2, 4, 8, 16, 59, 118, 236, 472, 944
801 : 1, 3, 9, 89, 267, 801
290 : 1, 2, 5, 10, 29, 58, 145, 290
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,944,801,290, is 1.
Now, the common factors can be found like this.
381:3x 127
944:2x 2x 2x 2x 59
801:3x 3x 89
290:2x 5x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 83546350560/(1x6)
LCM = 83546350560/6
LCM = 13924391760
Thus, we can understand that the LCM of 381,944,801,290 is 13924391760.
