Given numbers are 8,605,815,240
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 8,605,815,240 is 4733520.
Find LCM of 8,605,815,240 with Prime Factorization
| 2 | 8, 605, 815, 240 |
| 2 | 4, 605, 815, 120 |
| 2 | 2, 605, 815, 60 |
| 5 | 1, 605, 815, 30 |
| 1, 121, 163, 6 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 1 x 121 x 163 x 6 = 4733520
Therefore, the lowest common multiple of 8,605,815,240 is 4733520.
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.
8 x 605 x 815 x 240 = 946704000
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.
8 : 1, 2, 4, 8
605 : 1, 5, 11, 55, 121, 605
815 : 1, 5, 163, 815
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 8,605,815,240, is 1.
Now, the common factors can be found like this.
8:2x 2x 2
605:5x 11x 11
815:5x 163
240:2x 2x 2x 2x 3x 5
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 2x 5x 5 = 200
Therefore, the value for common factors is 200.
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 = 946704000/(1x200)
LCM = 946704000/200
LCM = 4733520
Thus, we can understand that the LCM of 8,605,815,240 is 4733520.
