Given numbers are 381,717,652,642,636
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 381,717,652,642,636 is 336689924028.
Find LCM of 381,717,652,642,636 with Prime Factorization
| 2 | 381, 717, 652, 642, 636 |
| 2 | 381, 717, 326, 321, 318 |
| 3 | 381, 717, 163, 321, 159 |
| 127, 239, 163, 107, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 127 x 239 x 163 x 107 x 53 = 336689924028
Therefore, the lowest common multiple of 381,717,652,642,636 is 336689924028.
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.
381 x 717 x 652 x 642 x 636 = 72725023590048
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.
381 : 1, 3, 127, 381
717 : 1, 3, 239, 717
652 : 1, 2, 4, 163, 326, 652
642 : 1, 2, 3, 6, 107, 214, 321, 642
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,717,652,642,636, is 1.
Now, the common factors can be found like this.
381:3x 127
717:3x 239
652:2x 2x 163
642:2x 3x 107
636:2x 2x 3x 53
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 2x 3x 3x 3 = 216
Therefore, the value for common factors is 216.
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 = 72725023590048/(1x216)
LCM = 72725023590048/216
LCM = 336689924028
Thus, we can understand that the LCM of 381,717,652,642,636 is 336689924028.
