Given numbers are 442,99,268,289
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 442,99,268,289 is 99680724.
Find LCM of 442,99,268,289 with Prime Factorization
| 2 | 442, 99, 268, 289 |
| 17 | 221, 99, 134, 289 |
| 13, 99, 134, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 13 x 99 x 134 x 17 = 99680724
Therefore, the lowest common multiple of 442,99,268,289 is 99680724.
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.
442 x 99 x 268 x 289 = 3389144616
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.
442 : 1, 2, 13, 17, 26, 34, 221, 442
99 : 1, 3, 9, 11, 33, 99
268 : 1, 2, 4, 67, 134, 268
289 : 1, 17, 289
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 442,99,268,289, is 1.
Now, the common factors can be found like this.
442:2x 13x 17
99:3x 3x 11
268:2x 2x 67
289:17x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 17 = 34
Therefore, the value for common factors is 34.
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 = 3389144616/(1x34)
LCM = 3389144616/34
LCM = 99680724
Thus, we can understand that the LCM of 442,99,268,289 is 99680724.
