Given numbers are 585,222,391,126,961
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 585,222,391,126,961 is 113863825530.
Find LCM of 585,222,391,126,961 with Prime Factorization
| 2 | 585, 222, 391, 126, 961 |
| 3 | 585, 111, 391, 63, 961 |
| 3 | 195, 37, 391, 21, 961 |
| 65, 37, 391, 7, 961 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 65 x 37 x 391 x 7 x 961 = 113863825530
Therefore, the lowest common multiple of 585,222,391,126,961 is 113863825530.
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.
585 x 222 x 391 x 126 x 961 = 6148646578620
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.
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
222 : 1, 2, 3, 6, 37, 74, 111, 222
391 : 1, 17, 23, 391
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
961 : 1, 31, 961
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 585,222,391,126,961, is 1.
Now, the common factors can be found like this.
585:3x 3x 5x 13
222:2x 3x 37
391:17x 23
126:2x 3x 3x 7
961:31x 31
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 = 6148646578620/(1x54)
LCM = 6148646578620/54
LCM = 113863825530
Thus, we can understand that the LCM of 585,222,391,126,961 is 113863825530.
