Given numbers are 923,872,247,442
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 923,872,247,442 is 259968488.
Find LCM of 923,872,247,442 with Prime Factorization
| 2 | 923, 872, 247, 442 |
| 13 | 923, 436, 247, 221 |
| 71, 436, 19, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 71 x 436 x 19 x 17 = 259968488
Therefore, the lowest common multiple of 923,872,247,442 is 259968488.
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.
923 x 872 x 247 x 442 = 87869348944
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.
923 : 1, 13, 71, 923
872 : 1, 2, 4, 8, 109, 218, 436, 872
247 : 1, 13, 19, 247
442 : 1, 2, 13, 17, 26, 34, 221, 442
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 923,872,247,442, is 1.
Now, the common factors can be found like this.
923:13x 71
872:2x 2x 2x 109
247:13x 19
442:2x 13x 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 13x 13 = 338
Therefore, the value for common factors is 338.
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 = 87869348944/(1x338)
LCM = 87869348944/338
LCM = 259968488
Thus, we can understand that the LCM of 923,872,247,442 is 259968488.
