Given numbers are 450,720,145,447
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 450,720,145,447 is 15555600.
Find LCM of 450,720,145,447 with Prime Factorization
| 2 | 450, 720, 145, 447 |
| 3 | 225, 360, 145, 447 |
| 3 | 75, 120, 145, 149 |
| 5 | 25, 40, 145, 149 |
| 5, 8, 29, 149 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 5 x 8 x 29 x 149 = 15555600
Therefore, the lowest common multiple of 450,720,145,447 is 15555600.
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 720 x 145 x 447 = 21000060000
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
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
145 : 1, 5, 29, 145
447 : 1, 3, 149, 447
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 450,720,145,447, is 1.
Now, the common factors can be found like this.
450:2x 3x 3x 5x 5
720:2x 2x 2x 2x 3x 3x 5
145:5x 29
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 3x 3x 3x 5x 5 = 1350
Therefore, the value for common factors is 1350.
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 = 21000060000/(1x1350)
LCM = 21000060000/1350
LCM = 15555600
Thus, we can understand that the LCM of 450,720,145,447 is 15555600.
