Given numbers are 863,642,418,107
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 863,642,418,107 is 115795614.
Find LCM of 863,642,418,107 with Prime Factorization
| 2 | 863, 642, 418, 107 |
| 107 | 863, 321, 209, 107 |
| 863, 3, 209, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 107 x 863 x 3 x 209 x 1 = 115795614
Therefore, the lowest common multiple of 863,642,418,107 is 115795614.
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.
863 x 642 x 418 x 107 = 24780261396
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.
863 : 1, 863
642 : 1, 2, 3, 6, 107, 214, 321, 642
418 : 1, 2, 11, 19, 22, 38, 209, 418
107 : 1, 107
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 863,642,418,107, is 1.
Now, the common factors can be found like this.
863:863
642:2x 3x 107
418:2x 11x 19
107:107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 107 = 214
Therefore, the value for common factors is 214.
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 = 24780261396/(1x214)
LCM = 24780261396/214
LCM = 115795614
Thus, we can understand that the LCM of 863,642,418,107 is 115795614.
