Given numbers are 861,808,303,115
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 861,808,303,115 is 80004120.
Find LCM of 861,808,303,115 with Prime Factorization
| 3 | 861, 808, 303, 115 |
| 101 | 287, 808, 101, 115 |
| 287, 8, 1, 115 |
Multiply the prime numbers at the bottom and the left side.
3 x 101 x 287 x 8 x 1 x 115 = 80004120
Therefore, the lowest common multiple of 861,808,303,115 is 80004120.
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.
861 x 808 x 303 x 115 = 24241248360
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.
861 : 1, 3, 7, 21, 41, 123, 287, 861
808 : 1, 2, 4, 8, 101, 202, 404, 808
303 : 1, 3, 101, 303
115 : 1, 5, 23, 115
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,808,303,115, is 1.
Now, the common factors can be found like this.
861:3x 7x 41
808:2x 2x 2x 101
303:3x 101
115:5x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 101 = 303
Therefore, the value for common factors is 303.
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 = 24241248360/(1x303)
LCM = 24241248360/303
LCM = 80004120
Thus, we can understand that the LCM of 861,808,303,115 is 80004120.
