Given numbers are 881,645,258,382
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 881,645,258,382 is 217069590.
Find LCM of 881,645,258,382 with Prime Factorization
| 2 | 881, 645, 258, 382 |
| 3 | 881, 645, 129, 191 |
| 43 | 881, 215, 43, 191 |
| 881, 5, 1, 191 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 43 x 881 x 5 x 1 x 191 = 217069590
Therefore, the lowest common multiple of 881,645,258,382 is 217069590.
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.
881 x 645 x 258 x 382 = 56003954220
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.
881 : 1, 881
645 : 1, 3, 5, 15, 43, 129, 215, 645
258 : 1, 2, 3, 6, 43, 86, 129, 258
382 : 1, 2, 191, 382
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 881,645,258,382, is 1.
Now, the common factors can be found like this.
881:881
645:3x 5x 43
258:2x 3x 43
382:2x 191
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 43 = 258
Therefore, the value for common factors is 258.
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 = 56003954220/(1x258)
LCM = 56003954220/258
LCM = 217069590
Thus, we can understand that the LCM of 881,645,258,382 is 217069590.
