Find LCM of 405,450,858,572 with Prime Factorization
| 2 | 405, 450, 858, 572 |
| 3 | 405, 225, 429, 286 |
| 3 | 135, 75, 143, 286 |
| 5 | 45, 25, 143, 286 |
| 11 | 9, 5, 143, 286 |
| 13 | 9, 5, 13, 26 |
| 9, 5, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 11 x 13 x 9 x 5 x 1 x 2 = 1158300
Therefore, the lowest common multiple of 405,450,858,572 is 1158300.
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.
405 x 450 x 858 x 572 = 89443926000
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.
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,450,858,572, is 1.
Now, the common factors can be found like this.
405:3x 3x 3x 3x 5
450:2x 3x 3x 5x 5
858:2x 3x 11x 13
572:2x 2x 11x 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 5x 11x 13 = 77220
Therefore, the value for common factors is 77220.
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 = 89443926000/(1x77220)
LCM = 89443926000/77220
LCM = 1158300
Thus, we can understand that the LCM of 405,450,858,572 is 1158300.
