Given numbers are 319,218,981,408
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 319,218,981,408 is 42559704.
Find LCM of 319,218,981,408 with Prime Factorization
| 2 | 319, 218, 981, 408 |
| 3 | 319, 109, 981, 204 |
| 109 | 319, 109, 327, 68 |
| 319, 1, 3, 68 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 109 x 319 x 1 x 3 x 68 = 42559704
Therefore, the lowest common multiple of 319,218,981,408 is 42559704.
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.
319 x 218 x 981 x 408 = 27834046416
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.
319 : 1, 11, 29, 319
218 : 1, 2, 109, 218
981 : 1, 3, 9, 109, 327, 981
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 319,218,981,408, is 1.
Now, the common factors can be found like this.
319:11x 29
218:2x 109
981:3x 3x 109
408:2x 2x 2x 3x 17
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 109 = 654
Therefore, the value for common factors is 654.
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 = 27834046416/(1x654)
LCM = 27834046416/654
LCM = 42559704
Thus, we can understand that the LCM of 319,218,981,408 is 42559704.
