Find LCM of 449,240,486,720 with Prime Factorization
| 2 | 449, 240, 486, 720 |
| 2 | 449, 120, 243, 360 |
| 2 | 449, 60, 243, 180 |
| 2 | 449, 30, 243, 90 |
| 3 | 449, 15, 243, 45 |
| 3 | 449, 5, 81, 15 |
| 5 | 449, 5, 27, 5 |
| 449, 1, 27, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 3 x 5 x 449 x 1 x 27 x 1 = 8728560
Therefore, the lowest common multiple of 449,240,486,720 is 8728560.
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.
449 x 240 x 486 x 720 = 37707379200
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.
449 : 1, 449
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 449,240,486,720, is 1.
Now, the common factors can be found like this.
449:449
240:2x 2x 2x 2x 3x 5
486:2x 3x 3x 3x 3x 3
720:2x 2x 2x 2x 3x 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 2x 2x 3x 3x 3x 5 = 4320
Therefore, the value for common factors is 4320.
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 = 37707379200/(1x4320)
LCM = 37707379200/4320
LCM = 8728560
Thus, we can understand that the LCM of 449,240,486,720 is 8728560.
