The LCM of 487,432,813,240 is 285070320.
Find LCM of 487,432,813,240 with Prime Factorization
| 2 | 487, 432, 813, 240 |
| 2 | 487, 216, 813, 120 |
| 2 | 487, 108, 813, 60 |
| 2 | 487, 54, 813, 30 |
| 3 | 487, 27, 813, 15 |
| 487, 9, 271, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 487 x 9 x 271 x 5 = 285070320
Therefore, the lowest common multiple of 487,432,813,240 is 285070320.
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.
487 x 432 x 813 x 240 = 41050126080
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.
487 : 1, 487
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
813 : 1, 3, 271, 813
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 487,432,813,240, is 1.
Now, the common factors can be found like this.
487:487
432:2x 2x 2x 2x 3x 3x 3
813:3x 271
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 2x 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 41050126080/(1x144)
LCM = 41050126080/144
LCM = 285070320
Thus, we can understand that the LCM of 487,432,813,240 is 285070320.
