Given numbers are 724,828,370,442,309
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 724,828,370,442,309 is 631117377540.
Find LCM of 724,828,370,442,309 with Prime Factorization
| 2 | 724, 828, 370, 442, 309 |
| 2 | 362, 414, 185, 221, 309 |
| 3 | 181, 207, 185, 221, 309 |
| 181, 69, 185, 221, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 181 x 69 x 185 x 221 x 103 = 631117377540
Therefore, the lowest common multiple of 724,828,370,442,309 is 631117377540.
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.
724 x 828 x 370 x 442 x 309 = 30293634121920
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.
724 : 1, 2, 4, 181, 362, 724
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
370 : 1, 2, 5, 10, 37, 74, 185, 370
442 : 1, 2, 13, 17, 26, 34, 221, 442
309 : 1, 3, 103, 309
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 724,828,370,442,309, is 1.
Now, the common factors can be found like this.
724:2x 2x 181
828:2x 2x 3x 3x 23
370:2x 5x 37
442:2x 13x 17
309:3x 103
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 2x 3 = 48
Therefore, the value for common factors is 48.
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 = 30293634121920/(1x48)
LCM = 30293634121920/48
LCM = 631117377540
Thus, we can understand that the LCM of 724,828,370,442,309 is 631117377540.
