Find LCM of 826,642,885,818,343 with Prime Factorization
| 2 | 826, 642, 885, 818, 343 |
| 3 | 413, 321, 885, 409, 343 |
| 7 | 413, 107, 295, 409, 343 |
| 59 | 59, 107, 295, 409, 49 |
| 1, 107, 5, 409, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 59 x 1 x 107 x 5 x 409 x 49 = 26568954930
Therefore, the lowest common multiple of 826,642,885,818,343 is 26568954930.
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.
826 x 642 x 885 x 818 x 343 = 131675740633080
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.
826 : 1, 2, 7, 14, 59, 118, 413, 826
642 : 1, 2, 3, 6, 107, 214, 321, 642
885 : 1, 3, 5, 15, 59, 177, 295, 885
818 : 1, 2, 409, 818
343 : 1, 7, 49, 343
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 826,642,885,818,343, is 1.
Now, the common factors can be found like this.
826:2x 7x 59
642:2x 3x 107
885:3x 5x 59
818:2x 409
343:7x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 7x 59 = 4956
Therefore, the value for common factors is 4956.
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 = 131675740633080/(1x4956)
LCM = 131675740633080/4956
LCM = 26568954930
Thus, we can understand that the LCM of 826,642,885,818,343 is 26568954930.
