Given numbers are 810,642,954,288
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 810,642,954,288 is 73496160.
Find LCM of 810,642,954,288 with Prime Factorization
| 2 | 810, 642, 954, 288 |
| 3 | 405, 321, 477, 144 |
| 3 | 135, 107, 159, 48 |
| 45, 107, 53, 16 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 45 x 107 x 53 x 16 = 73496160
Therefore, the lowest common multiple of 810,642,954,288 is 73496160.
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.
810 x 642 x 954 x 288 = 142876535040
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.
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
642 : 1, 2, 3, 6, 107, 214, 321, 642
954 : 1, 2, 3, 6, 9, 18, 53, 106, 159, 318, 477, 954
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
6 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 810,642,954,288, is 6.
Now, the common factors can be found like this.
810:2x 3x 3x 3x 3x 5
642:2x 3x 107
954:2x 3x 3x 53
288:2x 2x 2x 2x 2x 3x 3
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 3x 3 = 324
Therefore, the value for common factors is 324.
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 = 142876535040/(6x324)
LCM = 142876535040/1944
LCM = 73496160
Thus, we can understand that the LCM of 810,642,954,288 is 73496160.
