Given numbers are 411,230,394,690
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 411,230,394,690 is 18622410.
Find LCM of 411,230,394,690 with Prime Factorization
| 2 | 411, 230, 394, 690 |
| 3 | 411, 115, 197, 345 |
| 5 | 137, 115, 197, 115 |
| 23 | 137, 23, 197, 23 |
| 137, 1, 197, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 23 x 137 x 1 x 197 x 1 = 18622410
Therefore, the lowest common multiple of 411,230,394,690 is 18622410.
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.
411 x 230 x 394 x 690 = 25698925800
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.
411 : 1, 3, 137, 411
230 : 1, 2, 5, 10, 23, 46, 115, 230
394 : 1, 2, 197, 394
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 411,230,394,690, is 1.
Now, the common factors can be found like this.
411:3x 137
230:2x 5x 23
394:2x 197
690:2x 3x 5x 23
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 5x 23 = 1380
Therefore, the value for common factors is 1380.
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 = 25698925800/(1x1380)
LCM = 25698925800/1380
LCM = 18622410
Thus, we can understand that the LCM of 411,230,394,690 is 18622410.
