Given numbers are 390,806,886,751,609
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 390,806,886,751,609 is 816518449110.
Find LCM of 390,806,886,751,609 with Prime Factorization
| 2 | 390, 806, 886, 751, 609 |
| 3 | 195, 403, 443, 751, 609 |
| 13 | 65, 403, 443, 751, 203 |
| 5, 31, 443, 751, 203 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 5 x 31 x 443 x 751 x 203 = 816518449110
Therefore, the lowest common multiple of 390,806,886,751,609 is 816518449110.
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.
390 x 806 x 886 x 751 x 609 = 127376878061160
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.
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
806 : 1, 2, 13, 26, 31, 62, 403, 806
886 : 1, 2, 443, 886
751 : 1, 751
609 : 1, 3, 7, 21, 29, 87, 203, 609
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 390,806,886,751,609, is 1.
Now, the common factors can be found like this.
390:2x 3x 5x 13
806:2x 13x 31
886:2x 443
751:751
609:3x 7x 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 2x 3x 13 = 156
Therefore, the value for common factors is 156.
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 = 127376878061160/(1x156)
LCM = 127376878061160/156
LCM = 816518449110
Thus, we can understand that the LCM of 390,806,886,751,609 is 816518449110.
