Given numbers are 888,105,621,556,309
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 888,105,621,556,309 is 92109278520.
Find LCM of 888,105,621,556,309 with Prime Factorization
| 2 | 888, 105, 621, 556, 309 |
| 2 | 444, 105, 621, 278, 309 |
| 3 | 222, 105, 621, 139, 309 |
| 74, 35, 207, 139, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 74 x 35 x 207 x 139 x 103 = 92109278520
Therefore, the lowest common multiple of 888,105,621,556,309 is 92109278520.
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.
888 x 105 x 621 x 556 x 309 = 9947802080160
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.
888 : 1, 2, 3, 4, 6, 8, 12, 24, 37, 74, 111, 148, 222, 296, 444, 888
105 : 1, 3, 5, 7, 15, 21, 35, 105
621 : 1, 3, 9, 23, 27, 69, 207, 621
556 : 1, 2, 4, 139, 278, 556
309 : 1, 3, 103, 309
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 888,105,621,556,309, is 1.
Now, the common factors can be found like this.
888:2x 2x 2x 3x 37
105:3x 5x 7
621:3x 3x 3x 23
556:2x 2x 139
309:3x 103
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 3x 3 = 108
Therefore, the value for common factors is 108.
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 = 9947802080160/(1x108)
LCM = 9947802080160/108
LCM = 92109278520
Thus, we can understand that the LCM of 888,105,621,556,309 is 92109278520.
