Given numbers are 471,642,856,111,801
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 471,642,856,111,801 is 3982975704.
Find LCM of 471,642,856,111,801 with Prime Factorization
| 2 | 471, 642, 856, 111, 801 |
| 3 | 471, 321, 428, 111, 801 |
| 107 | 157, 107, 428, 37, 267 |
| 157, 1, 4, 37, 267 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 107 x 157 x 1 x 4 x 37 x 267 = 3982975704
Therefore, the lowest common multiple of 471,642,856,111,801 is 3982975704.
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.
471 x 642 x 856 x 111 x 801 = 23013633617712
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.
471 : 1, 3, 157, 471
642 : 1, 2, 3, 6, 107, 214, 321, 642
856 : 1, 2, 4, 8, 107, 214, 428, 856
111 : 1, 3, 37, 111
801 : 1, 3, 9, 89, 267, 801
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 471,642,856,111,801, is 1.
Now, the common factors can be found like this.
471:3x 157
642:2x 3x 107
856:2x 2x 2x 107
111:3x 37
801:3x 3x 89
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 3x 3x 107 = 5778
Therefore, the value for common factors is 5778.
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 = 23013633617712/(1x5778)
LCM = 23013633617712/5778
LCM = 3982975704
Thus, we can understand that the LCM of 471,642,856,111,801 is 3982975704.
