Given numbers are 319,813,407,646,855
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 319,813,407,646,855 is 92983679910.
Find LCM of 319,813,407,646,855 with Prime Factorization
| 3 | 319, 813, 407, 646, 855 |
| 11 | 319, 271, 407, 646, 285 |
| 19 | 29, 271, 37, 646, 285 |
| 29, 271, 37, 34, 15 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 19 x 29 x 271 x 37 x 34 x 15 = 92983679910
Therefore, the lowest common multiple of 319,813,407,646,855 is 92983679910.
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 813 x 407 x 646 x 855 = 58300767303570
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
813 : 1, 3, 271, 813
407 : 1, 11, 37, 407
646 : 1, 2, 17, 19, 34, 38, 323, 646
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 319,813,407,646,855, is 1.
Now, the common factors can be found like this.
319:11x 29
813:3x 271
407:11x 37
646:2x 17x 19
855:3x 3x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 19 = 627
Therefore, the value for common factors is 627.
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 = 58300767303570/(1x627)
LCM = 58300767303570/627
LCM = 92983679910
Thus, we can understand that the LCM of 319,813,407,646,855 is 92983679910.
