The LCM of 353,424,756,405 is 424320120.
Find LCM of 353,424,756,405 with Prime Factorization
| 2 | 353, 424, 756, 405 |
| 2 | 353, 212, 378, 405 |
| 3 | 353, 106, 189, 405 |
| 3 | 353, 106, 63, 135 |
| 3 | 353, 106, 21, 45 |
| 353, 106, 7, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 353 x 106 x 7 x 15 = 424320120
Therefore, the lowest common multiple of 353,424,756,405 is 424320120.
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.
353 x 424 x 756 x 405 = 45826572960
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.
353 : 1, 353
424 : 1, 2, 4, 8, 53, 106, 212, 424
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 353,424,756,405, is 1.
Now, the common factors can be found like this.
353:353
424:2x 2x 2x 53
756:2x 2x 3x 3x 3x 7
405:3x 3x 3x 3x 5
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 = 45826572960/(1x108)
LCM = 45826572960/108
LCM = 424320120
Thus, we can understand that the LCM of 353,424,756,405 is 424320120.
