Given numbers are 998,815,382,225
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 998,815,382,225 is 6990915150.
Find LCM of 998,815,382,225 with Prime Factorization
| 2 | 998, 815, 382, 225 |
| 5 | 499, 815, 191, 225 |
| 499, 163, 191, 45 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 499 x 163 x 191 x 45 = 6990915150
Therefore, the lowest common multiple of 998,815,382,225 is 6990915150.
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 815 x 382 x 225 = 69909151500
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
815 : 1, 5, 163, 815
382 : 1, 2, 191, 382
225 : 1, 3, 5, 9, 15, 25, 45, 75, 225
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 998,815,382,225, is 1.
Now, the common factors can be found like this.
998:2x 499
815:5x 163
382:2x 191
225:3x 3x 5x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 69909151500/(1x10)
LCM = 69909151500/10
LCM = 6990915150
Thus, we can understand that the LCM of 998,815,382,225 is 6990915150.
