Given numbers are 963,645,642,741,144
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 963,645,642,741,144 is 818241840.
Find LCM of 963,645,642,741,144 with Prime Factorization
| 2 | 963, 645, 642, 741, 144 |
| 3 | 963, 645, 321, 741, 72 |
| 3 | 107, 215, 321, 247, 24 |
| 107 | 107, 215, 107, 247, 8 |
| 1, 215, 1, 247, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 107 x 1 x 215 x 1 x 247 x 8 = 818241840
Therefore, the lowest common multiple of 963,645,642,741,144 is 818241840.
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.
963 x 645 x 642 x 741 x 144 = 42550212163680
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.
963 : 1, 3, 9, 107, 321, 963
645 : 1, 3, 5, 15, 43, 129, 215, 645
642 : 1, 2, 3, 6, 107, 214, 321, 642
741 : 1, 3, 13, 19, 39, 57, 247, 741
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 963,645,642,741,144, is 3.
Now, the common factors can be found like this.
963:3x 3x 107
645:3x 5x 43
642:2x 3x 107
741:3x 13x 19
144:2x 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 3x 3x 3x 3x 107 = 17334
Therefore, the value for common factors is 17334.
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 = 42550212163680/(3x17334)
LCM = 42550212163680/52002
LCM = 818241840
Thus, we can understand that the LCM of 963,645,642,741,144 is 818241840.
