Given numbers are 2040,9984
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 2040,9984 is 848640.
Find LCM of 2040,9984 with Prime Factorization
| 2 | 2040, 9984 |
| 2 | 1020, 4992 |
| 2 | 510, 2496 |
| 3 | 255, 1248 |
| 85, 416 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 85 x 416 = 848640
Therefore, the lowest common multiple of 2040,9984 is 848640.
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.
2040 x 9984 = 20367360
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.
2040 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 17, 20, 24, 30, 34, 40, 51, 60, 68, 85, 102, 120, 136, 170, 204, 255, 340, 408, 510, 680, 1020, 2040
9984 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 32, 39, 48, 52, 64, 78, 96, 104, 128, 156, 192, 208, 256, 312, 384, 416, 624, 768, 832, 1248, 1664, 2496, 3328, 4992, 9984
24 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 2040,9984, is 24.
Now, the common factors can be found like this.
2040:2x 2x 2x 3x 5x 17
9984:2x 2x 2x 2x 2x 2x 2x 2x 3x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
= 1
Therefore, the value for common factors is 1.
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 = 20367360/(24x1)
LCM = 20367360/24
LCM = 848640
Thus, we can understand that the LCM of 2040,9984 is 848640.
