Given numbers are 309,476,289,729,213
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 309,476,289,729,213 is 43139884284.
Find LCM of 309,476,289,729,213 with Prime Factorization
| 3 | 309, 476, 289, 729, 213 |
| 17 | 103, 476, 289, 243, 71 |
| 103, 28, 17, 243, 71 |
Multiply the prime numbers at the bottom and the left side.
3 x 17 x 103 x 28 x 17 x 243 x 71 = 43139884284
Therefore, the lowest common multiple of 309,476,289,729,213 is 43139884284.
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.
309 x 476 x 289 x 729 x 213 = 6600402295452
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.
309 : 1, 3, 103, 309
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
289 : 1, 17, 289
729 : 1, 3, 9, 27, 81, 243, 729
213 : 1, 3, 71, 213
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 309,476,289,729,213, is 1.
Now, the common factors can be found like this.
309:3x 103
476:2x 2x 7x 17
289:17x 17
729:3x 3x 3x 3x 3x 3
213:3x 71
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 17 = 153
Therefore, the value for common factors is 153.
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 = 6600402295452/(1x153)
LCM = 6600402295452/153
LCM = 43139884284
Thus, we can understand that the LCM of 309,476,289,729,213 is 43139884284.
