Given numbers are 450,840,806,447
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 450,840,806,447 is 756592200.
Find LCM of 450,840,806,447 with Prime Factorization
| 2 | 450, 840, 806, 447 |
| 3 | 225, 420, 403, 447 |
| 5 | 75, 140, 403, 149 |
| 15, 28, 403, 149 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 15 x 28 x 403 x 149 = 756592200
Therefore, the lowest common multiple of 450,840,806,447 is 756592200.
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.
450 x 840 x 806 x 447 = 136186596000
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.
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
806 : 1, 2, 13, 26, 31, 62, 403, 806
447 : 1, 3, 149, 447
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 450,840,806,447, is 1.
Now, the common factors can be found like this.
450:2x 3x 3x 5x 5
840:2x 2x 2x 3x 5x 7
806:2x 13x 31
447:3x 149
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 3x 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 136186596000/(1x180)
LCM = 136186596000/180
LCM = 756592200
Thus, we can understand that the LCM of 450,840,806,447 is 756592200.
