Given numbers are 859,105,800,805
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 859,105,800,805 is 331917600.
Find LCM of 859,105,800,805 with Prime Factorization
| 5 | 859, 105, 800, 805 |
| 7 | 859, 21, 160, 161 |
| 859, 3, 160, 23 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 859 x 3 x 160 x 23 = 331917600
Therefore, the lowest common multiple of 859,105,800,805 is 331917600.
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 105 x 800 x 805 = 58085580000
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
105 : 1, 3, 5, 7, 15, 21, 35, 105
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
805 : 1, 5, 7, 23, 35, 115, 161, 805
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 859,105,800,805, is 1.
Now, the common factors can be found like this.
859:859
105:3x 5x 7
800:2x 2x 2x 2x 2x 5x 5
805:5x 7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5x 7 = 175
Therefore, the value for common factors is 175.
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 = 58085580000/(1x175)
LCM = 58085580000/175
LCM = 331917600
Thus, we can understand that the LCM of 859,105,800,805 is 331917600.
