Given numbers are 807,405,128,206,738
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 807,405,128,206,738 is 58889566080.
Find LCM of 807,405,128,206,738 with Prime Factorization
| 2 | 807, 405, 128, 206, 738 |
| 3 | 807, 405, 64, 103, 369 |
| 3 | 269, 135, 64, 103, 123 |
| 269, 45, 64, 103, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 269 x 45 x 64 x 103 x 41 = 58889566080
Therefore, the lowest common multiple of 807,405,128,206,738 is 58889566080.
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.
807 x 405 x 128 x 206 x 738 = 6360073136640
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.
807 : 1, 3, 269, 807
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
128 : 1, 2, 4, 8, 16, 32, 64, 128
206 : 1, 2, 103, 206
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 807,405,128,206,738, is 1.
Now, the common factors can be found like this.
807:3x 269
405:3x 3x 3x 3x 5
128:2x 2x 2x 2x 2x 2x 2
206:2x 103
738:2x 3x 3x 41
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 3x 3x 3 = 108
Therefore, the value for common factors is 108.
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 = 6360073136640/(1x108)
LCM = 6360073136640/108
LCM = 58889566080
Thus, we can understand that the LCM of 807,405,128,206,738 is 58889566080.
