Find LCM of 115,429,585,945 with Prime Factorization
| 3 | 115, 429, 585, 945 |
| 3 | 115, 143, 195, 315 |
| 5 | 115, 143, 65, 105 |
| 13 | 23, 143, 13, 21 |
| 23, 11, 1, 21 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 13 x 23 x 11 x 1 x 21 = 3108105
Therefore, the lowest common multiple of 115,429,585,945 is 3108105.
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.
115 x 429 x 585 x 945 = 27273621375
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.
115 : 1, 5, 23, 115
429 : 1, 3, 11, 13, 33, 39, 143, 429
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 115,429,585,945, is 1.
Now, the common factors can be found like this.
115:5x 23
429:3x 11x 13
585:3x 3x 5x 13
945:3x 3x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 5x 5x 13 = 8775
Therefore, the value for common factors is 8775.
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 = 27273621375/(1x8775)
LCM = 27273621375/8775
LCM = 3108105
Thus, we can understand that the LCM of 115,429,585,945 is 3108105.
