Given numbers are 258,991,622,432,215
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 258,991,622,432,215 is 28625708880.
Find LCM of 258,991,622,432,215 with Prime Factorization
| 2 | 258, 991, 622, 432, 215 |
| 3 | 129, 991, 311, 216, 215 |
| 43 | 43, 991, 311, 72, 215 |
| 1, 991, 311, 72, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 43 x 1 x 991 x 311 x 72 x 5 = 28625708880
Therefore, the lowest common multiple of 258,991,622,432,215 is 28625708880.
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.
258 x 991 x 622 x 432 x 215 = 14770865782080
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.
258 : 1, 2, 3, 6, 43, 86, 129, 258
991 : 1, 991
622 : 1, 2, 311, 622
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
215 : 1, 5, 43, 215
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 258,991,622,432,215, is 1.
Now, the common factors can be found like this.
258:2x 3x 43
991:991
622:2x 311
432:2x 2x 2x 2x 3x 3x 3
215:5x 43
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 3x 43 = 516
Therefore, the value for common factors is 516.
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 = 14770865782080/(1x516)
LCM = 14770865782080/516
LCM = 28625708880
Thus, we can understand that the LCM of 258,991,622,432,215 is 28625708880.
