Given numbers are 900,645,458,828
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 900,645,458,828 is 203832900.
Find LCM of 900,645,458,828 with Prime Factorization
| 2 | 900, 645, 458, 828 |
| 2 | 450, 645, 229, 414 |
| 3 | 225, 645, 229, 207 |
| 3 | 75, 215, 229, 69 |
| 5 | 25, 215, 229, 23 |
| 5, 43, 229, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 5 x 43 x 229 x 23 = 203832900
Therefore, the lowest common multiple of 900,645,458,828 is 203832900.
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.
900 x 645 x 458 x 828 = 220139532000
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.
900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900
645 : 1, 3, 5, 15, 43, 129, 215, 645
458 : 1, 2, 229, 458
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 900,645,458,828, is 1.
Now, the common factors can be found like this.
900:2x 2x 3x 3x 5x 5
645:3x 5x 43
458:2x 229
828:2x 2x 3x 3x 23
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 3x 5 = 1080
Therefore, the value for common factors is 1080.
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 = 220139532000/(1x1080)
LCM = 220139532000/1080
LCM = 203832900
Thus, we can understand that the LCM of 900,645,458,828 is 203832900.
