Given numbers are 391,289,767,858,986
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 391,289,767,858,986 is 9758048586.
Find LCM of 391,289,767,858,986 with Prime Factorization
| 2 | 391, 289, 767, 858, 986 |
| 13 | 391, 289, 767, 429, 493 |
| 17 | 391, 289, 59, 33, 493 |
| 23, 17, 59, 33, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 17 x 23 x 17 x 59 x 33 x 29 = 9758048586
Therefore, the lowest common multiple of 391,289,767,858,986 is 9758048586.
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.
391 x 289 x 767 x 858 x 986 = 73321977075204
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.
391 : 1, 17, 23, 391
289 : 1, 17, 289
767 : 1, 13, 59, 767
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
986 : 1, 2, 17, 29, 34, 58, 493, 986
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,289,767,858,986, is 1.
Now, the common factors can be found like this.
391:17x 23
289:17x 17
767:13x 59
858:2x 3x 11x 13
986:2x 17x 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 13x 17x 17 = 7514
Therefore, the value for common factors is 7514.
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 = 73321977075204/(1x7514)
LCM = 73321977075204/7514
LCM = 9758048586
Thus, we can understand that the LCM of 391,289,767,858,986 is 9758048586.
