The LCM of 418,351,481,117 is 5428566.
Find LCM of 418,351,481,117 with Prime Factorization
| 3 | 418, 351, 481, 117 |
| 3 | 418, 117, 481, 39 |
| 13 | 418, 13, 481, 39 |
| 418, 1, 37, 3 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 13 x 418 x 1 x 37 x 3 = 5428566
Therefore, the lowest common multiple of 418,351,481,117 is 5428566.
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.
418 x 351 x 481 x 117 = 8256848886
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.
418 : 1, 2, 11, 19, 22, 38, 209, 418
351 : 1, 3, 9, 13, 27, 39, 117, 351
481 : 1, 13, 37, 481
117 : 1, 3, 9, 13, 39, 117
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,351,481,117, is 1.
Now, the common factors can be found like this.
418:2x 11x 19
351:3x 3x 3x 13
481:13x 37
117:3x 3x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 13x 13 = 1521
Therefore, the value for common factors is 1521.
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 = 8256848886/(1x1521)
LCM = 8256848886/1521
LCM = 5428566
Thus, we can understand that the LCM of 418,351,481,117 is 5428566.
