Given numbers are 8,286,221,374
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 8,286,221,374 is 19448.
Find LCM of 8,286,221,374 with Prime Factorization
| 2 | 8, 286, 221, 374 |
| 11 | 4, 143, 221, 187 |
| 13 | 4, 13, 221, 17 |
| 17 | 4, 1, 17, 17 |
| 4, 1, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 13 x 17 x 4 x 1 x 1 x 1 = 19448
Therefore, the lowest common multiple of 8,286,221,374 is 19448.
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.
8 x 286 x 221 x 374 = 189112352
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.
8 : 1, 2, 4, 8
286 : 1, 2, 11, 13, 22, 26, 143, 286
221 : 1, 13, 17, 221
374 : 1, 2, 11, 17, 22, 34, 187, 374
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 8,286,221,374, is 1.
Now, the common factors can be found like this.
8:2x 2x 2
286:2x 11x 13
221:13x 17
374:2x 11x 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 2x 11x 13x 17 = 9724
Therefore, the value for common factors is 9724.
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 = 189112352/(1x9724)
LCM = 189112352/9724
LCM = 19448
Thus, we can understand that the LCM of 8,286,221,374 is 19448.
