Given numbers are 806,786,245,685,906
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 806,786,245,685,906 is 1605429322770.
Find LCM of 806,786,245,685,906 with Prime Factorization
| 2 | 806, 786, 245, 685, 906 |
| 3 | 403, 393, 245, 685, 453 |
| 5 | 403, 131, 245, 685, 151 |
| 403, 131, 49, 137, 151 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 403 x 131 x 49 x 137 x 151 = 1605429322770
Therefore, the lowest common multiple of 806,786,245,685,906 is 1605429322770.
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.
806 x 786 x 245 x 685 x 906 = 96325759366200
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.
806 : 1, 2, 13, 26, 31, 62, 403, 806
786 : 1, 2, 3, 6, 131, 262, 393, 786
245 : 1, 5, 7, 35, 49, 245
685 : 1, 5, 137, 685
906 : 1, 2, 3, 6, 151, 302, 453, 906
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 806,786,245,685,906, is 1.
Now, the common factors can be found like this.
806:2x 13x 31
786:2x 3x 131
245:5x 7x 7
685:5x 137
906:2x 3x 151
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 5 = 60
Therefore, the value for common factors is 60.
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 = 96325759366200/(1x60)
LCM = 96325759366200/60
LCM = 1605429322770
Thus, we can understand that the LCM of 806,786,245,685,906 is 1605429322770.
