Given numbers are 247,872,754,286
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 247,872,754,286 is 68707496.
Find LCM of 247,872,754,286 with Prime Factorization
| 2 | 247, 872, 754, 286 |
| 13 | 247, 436, 377, 143 |
| 19, 436, 29, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 19 x 436 x 29 x 11 = 68707496
Therefore, the lowest common multiple of 247,872,754,286 is 68707496.
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.
247 x 872 x 754 x 286 = 46446267296
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.
247 : 1, 13, 19, 247
872 : 1, 2, 4, 8, 109, 218, 436, 872
754 : 1, 2, 13, 26, 29, 58, 377, 754
286 : 1, 2, 11, 13, 22, 26, 143, 286
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,872,754,286, is 1.
Now, the common factors can be found like this.
247:13x 19
872:2x 2x 2x 109
754:2x 13x 29
286:2x 11x 13
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 13x 13 = 676
Therefore, the value for common factors is 676.
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 = 46446267296/(1x676)
LCM = 46446267296/676
LCM = 68707496
Thus, we can understand that the LCM of 247,872,754,286 is 68707496.
