Given numbers are 363,825,845,987,561
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 363,825,845,987,561 is 8577844275.
Find LCM of 363,825,845,987,561 with Prime Factorization
| 3 | 363, 825, 845, 987, 561 |
| 5 | 121, 275, 845, 329, 187 |
| 11 | 121, 55, 169, 329, 187 |
| 11, 5, 169, 329, 17 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 11 x 5 x 169 x 329 x 17 = 8577844275
Therefore, the lowest common multiple of 363,825,845,987,561 is 8577844275.
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 825 x 845 x 987 x 561 = 140119086232125
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
825 : 1, 3, 5, 11, 15, 25, 33, 55, 75, 165, 275, 825
845 : 1, 5, 13, 65, 169, 845
987 : 1, 3, 7, 21, 47, 141, 329, 987
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 363,825,845,987,561, is 1.
Now, the common factors can be found like this.
363:3x 11x 11
825:3x 5x 5x 11
845:5x 13x 13
987:3x 7x 47
561:3x 11x 17
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 3x 5x 11x 11 = 16335
Therefore, the value for common factors is 16335.
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 = 140119086232125/(1x16335)
LCM = 140119086232125/16335
LCM = 8577844275
Thus, we can understand that the LCM of 363,825,845,987,561 is 8577844275.
