Given numbers are 345,258,843,817
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 345,258,843,817 is 158408130.
Find LCM of 345,258,843,817 with Prime Factorization
| 3 | 345, 258, 843, 817 |
| 43 | 115, 86, 281, 817 |
| 115, 2, 281, 19 |
Multiply the prime numbers at the bottom and the left side.
3 x 43 x 115 x 2 x 281 x 19 = 158408130
Therefore, the lowest common multiple of 345,258,843,817 is 158408130.
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.
345 x 258 x 843 x 817 = 61303946310
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.
345 : 1, 3, 5, 15, 23, 69, 115, 345
258 : 1, 2, 3, 6, 43, 86, 129, 258
843 : 1, 3, 281, 843
817 : 1, 19, 43, 817
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 345,258,843,817, is 1.
Now, the common factors can be found like this.
345:3x 5x 23
258:2x 3x 43
843:3x 281
817:19x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 43 = 387
Therefore, the value for common factors is 387.
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 = 61303946310/(1x387)
LCM = 61303946310/387
LCM = 158408130
Thus, we can understand that the LCM of 345,258,843,817 is 158408130.
