Given numbers are 261,663,605,888,822
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 261,663,605,888,822 is 1415143346760.
Find LCM of 261,663,605,888,822 with Prime Factorization
| 2 | 261, 663, 605, 888, 822 |
| 3 | 261, 663, 605, 444, 411 |
| 87, 221, 605, 148, 137 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 87 x 221 x 605 x 148 x 137 = 1415143346760
Therefore, the lowest common multiple of 261,663,605,888,822 is 1415143346760.
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.
261 x 663 x 605 x 888 x 822 = 76417740725040
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.
261 : 1, 3, 9, 29, 87, 261
663 : 1, 3, 13, 17, 39, 51, 221, 663
605 : 1, 5, 11, 55, 121, 605
888 : 1, 2, 3, 4, 6, 8, 12, 24, 37, 74, 111, 148, 222, 296, 444, 888
822 : 1, 2, 3, 6, 137, 274, 411, 822
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 261,663,605,888,822, is 1.
Now, the common factors can be found like this.
261:3x 3x 29
663:3x 13x 17
605:5x 11x 11
888:2x 2x 2x 3x 37
822:2x 3x 137
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 3 = 54
Therefore, the value for common factors is 54.
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 = 76417740725040/(1x54)
LCM = 76417740725040/54
LCM = 1415143346760
Thus, we can understand that the LCM of 261,663,605,888,822 is 1415143346760.
