Given numbers are 391,846,280,662
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 391,846,280,662 is 15328623240.
Find LCM of 391,846,280,662 with Prime Factorization
| 2 | 391, 846, 280, 662 |
| 391, 423, 140, 331 |
Multiply the prime numbers at the bottom and the left side.
2 x 391 x 423 x 140 x 331 = 15328623240
Therefore, the lowest common multiple of 391,846,280,662 is 15328623240.
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 846 x 280 x 662 = 61314492960
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
846 : 1, 2, 3, 6, 9, 18, 47, 94, 141, 282, 423, 846
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
662 : 1, 2, 331, 662
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,846,280,662, is 1.
Now, the common factors can be found like this.
391:17x 23
846:2x 3x 3x 47
280:2x 2x 2x 5x 7
662:2x 331
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 61314492960/(1x4)
LCM = 61314492960/4
LCM = 15328623240
Thus, we can understand that the LCM of 391,846,280,662 is 15328623240.
