Given numbers are 667,741,870,855
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 667,741,870,855 is 14827410.
Find LCM of 667,741,870,855 with Prime Factorization
| 3 | 667, 741, 870, 855 |
| 5 | 667, 247, 290, 285 |
| 19 | 667, 247, 58, 57 |
| 29 | 667, 13, 58, 3 |
| 23, 13, 2, 3 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 19 x 29 x 23 x 13 x 2 x 3 = 14827410
Therefore, the lowest common multiple of 667,741,870,855 is 14827410.
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.
667 x 741 x 870 x 855 = 367645630950
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.
667 : 1, 23, 29, 667
741 : 1, 3, 13, 19, 39, 57, 247, 741
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 667,741,870,855, is 1.
Now, the common factors can be found like this.
667:23x 29
741:3x 13x 19
870:2x 3x 5x 29
855:3x 3x 5x 19
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 5x 19x 29 = 24795
Therefore, the value for common factors is 24795.
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 = 367645630950/(1x24795)
LCM = 367645630950/24795
LCM = 14827410
Thus, we can understand that the LCM of 667,741,870,855 is 14827410.
