Given numbers are 668,447,839,105
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 668,447,839,105 is 8768271540.
Find LCM of 668,447,839,105 with Prime Factorization
| 3 | 668, 447, 839, 105 |
| 668, 149, 839, 35 |
Multiply the prime numbers at the bottom and the left side.
3 x 668 x 149 x 839 x 35 = 8768271540
Therefore, the lowest common multiple of 668,447,839,105 is 8768271540.
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.
668 x 447 x 839 x 105 = 26304814620
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.
668 : 1, 2, 4, 167, 334, 668
447 : 1, 3, 149, 447
839 : 1, 839
105 : 1, 3, 5, 7, 15, 21, 35, 105
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,447,839,105, is 1.
Now, the common factors can be found like this.
668:2x 2x 167
447:3x 149
839:839
105:3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 26304814620/(1x3)
LCM = 26304814620/3
LCM = 8768271540
Thus, we can understand that the LCM of 668,447,839,105 is 8768271540.
