Given numbers are 486,447,447,605
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 486,447,447,605 is 43810470.
Find LCM of 486,447,447,605 with Prime Factorization
| 3 | 486, 447, 447, 605 |
| 149 | 162, 149, 149, 605 |
| 162, 1, 1, 605 |
Multiply the prime numbers at the bottom and the left side.
3 x 149 x 162 x 1 x 1 x 605 = 43810470
Therefore, the lowest common multiple of 486,447,447,605 is 43810470.
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.
486 x 447 x 447 x 605 = 58749840270
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.
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
447 : 1, 3, 149, 447
447 : 1, 3, 149, 447
605 : 1, 5, 11, 55, 121, 605
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 486,447,447,605, is 1.
Now, the common factors can be found like this.
486:2x 3x 3x 3x 3x 3
447:3x 149
447:3x 149
605:5x 11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 149 = 1341
Therefore, the value for common factors is 1341.
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 = 58749840270/(1x1341)
LCM = 58749840270/1341
LCM = 43810470
Thus, we can understand that the LCM of 486,447,447,605 is 43810470.
