Given numbers are 806,386,435,558
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 806,386,435,558 is 203003190.
Find LCM of 806,386,435,558 with Prime Factorization
| 2 | 806, 386, 435, 558 |
| 3 | 403, 193, 435, 279 |
| 31 | 403, 193, 145, 93 |
| 13, 193, 145, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 31 x 13 x 193 x 145 x 3 = 203003190
Therefore, the lowest common multiple of 806,386,435,558 is 203003190.
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 386 x 435 x 558 = 75517186680
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
386 : 1, 2, 193, 386
435 : 1, 3, 5, 15, 29, 87, 145, 435
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 806,386,435,558, is 1.
Now, the common factors can be found like this.
806:2x 13x 31
386:2x 193
435:3x 5x 29
558:2x 3x 3x 31
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 31 = 372
Therefore, the value for common factors is 372.
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 = 75517186680/(1x372)
LCM = 75517186680/372
LCM = 203003190
Thus, we can understand that the LCM of 806,386,435,558 is 203003190.
