Given numbers are 668,644,869,405,327
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 668,644,869,405,327 is 4125756913740.
Find LCM of 668,644,869,405,327 with Prime Factorization
| 2 | 668, 644, 869, 405, 327 |
| 2 | 334, 322, 869, 405, 327 |
| 3 | 167, 161, 869, 405, 327 |
| 167, 161, 869, 135, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 167 x 161 x 869 x 135 x 109 = 4125756913740
Therefore, the lowest common multiple of 668,644,869,405,327 is 4125756913740.
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 644 x 869 x 405 x 327 = 49509082964880
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
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
869 : 1, 11, 79, 869
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
327 : 1, 3, 109, 327
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,644,869,405,327, is 1.
Now, the common factors can be found like this.
668:2x 2x 167
644:2x 2x 7x 23
869:11x 79
405:3x 3x 3x 3x 5
327:3x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3 = 12
Therefore, the value for common factors is 12.
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 = 49509082964880/(1x12)
LCM = 49509082964880/12
LCM = 4125756913740
Thus, we can understand that the LCM of 668,644,869,405,327 is 4125756913740.
