Given numbers are 331,219,715,858
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 331,219,715,858 is 103659270.
Find LCM of 331,219,715,858 with Prime Factorization
| 3 | 331, 219, 715, 858 |
| 11 | 331, 73, 715, 286 |
| 13 | 331, 73, 65, 26 |
| 331, 73, 5, 2 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 13 x 331 x 73 x 5 x 2 = 103659270
Therefore, the lowest common multiple of 331,219,715,858 is 103659270.
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.
331 x 219 x 715 x 858 = 44469826830
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.
331 : 1, 331
219 : 1, 3, 73, 219
715 : 1, 5, 11, 13, 55, 65, 143, 715
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 331,219,715,858, is 1.
Now, the common factors can be found like this.
331:331
219:3x 73
715:5x 11x 13
858:2x 3x 11x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 13 = 429
Therefore, the value for common factors is 429.
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 = 44469826830/(1x429)
LCM = 44469826830/429
LCM = 103659270
Thus, we can understand that the LCM of 331,219,715,858 is 103659270.
