Given numbers are 859,203,309,915
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 859,203,309,915 is 16434160365.
Find LCM of 859,203,309,915 with Prime Factorization
| 3 | 859, 203, 309, 915 |
| 859, 203, 103, 305 |
Multiply the prime numbers at the bottom and the left side.
3 x 859 x 203 x 103 x 305 = 16434160365
Therefore, the lowest common multiple of 859,203,309,915 is 16434160365.
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.
859 x 203 x 309 x 915 = 49302481095
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.
859 : 1, 859
203 : 1, 7, 29, 203
309 : 1, 3, 103, 309
915 : 1, 3, 5, 15, 61, 183, 305, 915
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 859,203,309,915, is 1.
Now, the common factors can be found like this.
859:859
203:7x 29
309:3x 103
915:3x 5x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 49302481095/(1x3)
LCM = 49302481095/3
LCM = 16434160365
Thus, we can understand that the LCM of 859,203,309,915 is 16434160365.
