Given numbers are 207,390,405,512
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 207,390,405,512 is 62000640.
Find LCM of 207,390,405,512 with Prime Factorization
2 | 207, 390, 405, 512 |
3 | 207, 195, 405, 256 |
3 | 69, 65, 135, 256 |
5 | 23, 65, 45, 256 |
23, 13, 9, 256 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 23 x 13 x 9 x 256 = 62000640
Therefore, the lowest common multiple of 207,390,405,512 is 62000640.
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.
207 x 390 x 405 x 512 = 16740172800
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.
207 : 1, 3, 9, 23, 69, 207
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
512 : 1, 2, 4, 8, 16, 32, 64, 128, 256, 512
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 207,390,405,512, is 1.
Now, the common factors can be found like this.
207:3x 3x 23
390:2x 3x 5x 13
405:3x 3x 3x 3x 5
512:2x 2x 2x 2x 2x 2x 2x 2x 2
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 3x 5 = 270
Therefore, the value for common factors is 270.
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 = 16740172800/(1x270)
LCM = 16740172800/270
LCM = 62000640
Thus, we can understand that the LCM of 207,390,405,512 is 62000640.
