Given numbers are 657,819,451,906,801
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 657,819,451,906,801 is 724736698686.
Find LCM of 657,819,451,906,801 with Prime Factorization
| 3 | 657, 819, 451, 906, 801 |
| 3 | 219, 273, 451, 302, 267 |
| 73, 91, 451, 302, 89 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 73 x 91 x 451 x 302 x 89 = 724736698686
Therefore, the lowest common multiple of 657,819,451,906,801 is 724736698686.
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.
657 x 819 x 451 x 906 x 801 = 176111017780698
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.
657 : 1, 3, 9, 73, 219, 657
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
451 : 1, 11, 41, 451
906 : 1, 2, 3, 6, 151, 302, 453, 906
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 657,819,451,906,801, is 1.
Now, the common factors can be found like this.
657:3x 3x 73
819:3x 3x 7x 13
451:11x 41
906:2x 3x 151
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.
3x 3x 3x 3x 3 = 243
Therefore, the value for common factors is 243.
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 = 176111017780698/(1x243)
LCM = 176111017780698/243
LCM = 724736698686
Thus, we can understand that the LCM of 657,819,451,906,801 is 724736698686.
