Given numbers are 418,508,121,817
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 418,508,121,817 is 50219356.
Find LCM of 418,508,121,817 with Prime Factorization
| 2 | 418, 508, 121, 817 |
| 11 | 209, 254, 121, 817 |
| 19 | 19, 254, 11, 817 |
| 1, 254, 11, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 19 x 1 x 254 x 11 x 43 = 50219356
Therefore, the lowest common multiple of 418,508,121,817 is 50219356.
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 508 x 121 x 817 = 20991690808
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
508 : 1, 2, 4, 127, 254, 508
121 : 1, 11, 121
817 : 1, 19, 43, 817
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,508,121,817, is 1.
Now, the common factors can be found like this.
418:2x 11x 19
508:2x 2x 127
121:11x 11
817:19x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 19 = 418
Therefore, the value for common factors is 418.
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 = 20991690808/(1x418)
LCM = 20991690808/418
LCM = 50219356
Thus, we can understand that the LCM of 418,508,121,817 is 50219356.
