Given numbers are 999,858,821,982,561
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 999,858,821,982,561 is 1957965756318.
Find LCM of 999,858,821,982,561 with Prime Factorization
| 2 | 999, 858, 821, 982, 561 |
| 3 | 999, 429, 821, 491, 561 |
| 11 | 333, 143, 821, 491, 187 |
| 333, 13, 821, 491, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 333 x 13 x 821 x 491 x 17 = 1957965756318
Therefore, the lowest common multiple of 999,858,821,982,561 is 1957965756318.
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.
999 x 858 x 821 x 982 x 561 = 387677219750964
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.
999 : 1, 3, 9, 27, 37, 111, 333, 999
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
821 : 1, 821
982 : 1, 2, 491, 982
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 999,858,821,982,561, is 1.
Now, the common factors can be found like this.
999:3x 3x 3x 37
858:2x 3x 11x 13
821:821
982:2x 491
561:3x 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 3x 3x 11 = 198
Therefore, the value for common factors is 198.
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 = 387677219750964/(1x198)
LCM = 387677219750964/198
LCM = 1957965756318
Thus, we can understand that the LCM of 999,858,821,982,561 is 1957965756318.
