Given numbers are 363,605,891,861
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 363,605,891,861 is 14064435.
Find LCM of 363,605,891,861 with Prime Factorization
| 3 | 363, 605, 891, 861 |
| 11 | 121, 605, 297, 287 |
| 11 | 11, 55, 27, 287 |
| 1, 5, 27, 287 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 11 x 1 x 5 x 27 x 287 = 14064435
Therefore, the lowest common multiple of 363,605,891,861 is 14064435.
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.
363 x 605 x 891 x 861 = 168477866865
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.
363 : 1, 3, 11, 33, 121, 363
605 : 1, 5, 11, 55, 121, 605
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 363,605,891,861, is 1.
Now, the common factors can be found like this.
363:3x 11x 11
605:5x 11x 11
891:3x 3x 3x 3x 11
861:3x 7x 41
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 11x 11x 11 = 11979
Therefore, the value for common factors is 11979.
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 = 168477866865/(1x11979)
LCM = 168477866865/11979
LCM = 14064435
Thus, we can understand that the LCM of 363,605,891,861 is 14064435.
