Given numbers are 450,729,249,828
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 450,729,249,828 is 139166100.
Find LCM of 450,729,249,828 with Prime Factorization
| 2 | 450, 729, 249, 828 |
| 3 | 225, 729, 249, 414 |
| 3 | 75, 243, 83, 138 |
| 25, 81, 83, 46 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 25 x 81 x 83 x 46 = 139166100
Therefore, the lowest common multiple of 450,729,249,828 is 139166100.
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.
450 x 729 x 249 x 828 = 67634724600
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.
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
729 : 1, 3, 9, 27, 81, 243, 729
249 : 1, 3, 83, 249
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 450,729,249,828, is 3.
Now, the common factors can be found like this.
450:2x 3x 3x 5x 5
729:3x 3x 3x 3x 3x 3
249:3x 83
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 3x 3x 3x 3 = 162
Therefore, the value for common factors is 162.
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 = 67634724600/(3x162)
LCM = 67634724600/486
LCM = 139166100
Thus, we can understand that the LCM of 450,729,249,828 is 139166100.
