Find LCM of 236,405,442,391,702 with Prime Factorization
| 2 | 236, 405, 442, 391, 702 |
| 3 | 118, 405, 221, 391, 351 |
| 3 | 118, 135, 221, 391, 117 |
| 3 | 118, 45, 221, 391, 39 |
| 13 | 118, 15, 221, 391, 13 |
| 17 | 118, 15, 17, 391, 1 |
| 118, 15, 1, 23, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 13 x 17 x 118 x 15 x 1 x 23 x 1 = 485833140
Therefore, the lowest common multiple of 236,405,442,391,702 is 485833140.
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.
236 x 405 x 442 x 391 x 702 = 11595865385520
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.
236 : 1, 2, 4, 59, 118, 236
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
442 : 1, 2, 13, 17, 26, 34, 221, 442
391 : 1, 17, 23, 391
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 236,405,442,391,702, is 1.
Now, the common factors can be found like this.
236:2x 2x 59
405:3x 3x 3x 3x 5
442:2x 13x 17
391:17x 23
702:2x 3x 3x 3x 13
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 3x 3x 13x 17 = 23868
Therefore, the value for common factors is 23868.
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 = 11595865385520/(1x23868)
LCM = 11595865385520/23868
LCM = 485833140
Thus, we can understand that the LCM of 236,405,442,391,702 is 485833140.
