Given numbers are 998,912,891
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 998,912,891 is 135161136.
Find LCM of 998,912,891 with Prime Factorization
| 2 | 998, 912, 891 |
| 3 | 499, 456, 891 |
| 499, 152, 297 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 499 x 152 x 297 = 135161136
Therefore, the lowest common multiple of 998,912,891 is 135161136.
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.
998 x 912 x 891 = 810966816
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.
998 : 1, 2, 499, 998
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 998,912,891, is 1.
Now, the common factors can be found like this.
998:2x 499
912:2x 2x 2x 2x 3x 19
891:3x 3x 3x 3x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 810966816/(1x6)
LCM = 810966816/6
LCM = 135161136
Thus, we can understand that the LCM of 998,912,891 is 135161136.
