The LCM of 413,561,707,649,815 is 19071809295.
Find LCM of 413,561,707,649,815 with Prime Factorization
| 7 | 413, 561, 707, 649, 815 |
| 11 | 59, 561, 101, 649, 815 |
| 59 | 59, 51, 101, 59, 815 |
| 1, 51, 101, 1, 815 |
Multiply the prime numbers at the bottom and the left side.
7 x 11 x 59 x 1 x 51 x 101 x 1 x 815 = 19071809295
Therefore, the lowest common multiple of 413,561,707,649,815 is 19071809295.
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.
413 x 561 x 707 x 649 x 815 = 86643229627185
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.
413 : 1, 7, 59, 413
561 : 1, 3, 11, 17, 33, 51, 187, 561
707 : 1, 7, 101, 707
649 : 1, 11, 59, 649
815 : 1, 5, 163, 815
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 413,561,707,649,815, is 1.
Now, the common factors can be found like this.
413:7x 59
561:3x 11x 17
707:7x 101
649:11x 59
815:5x 163
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 11x 59 = 4543
Therefore, the value for common factors is 4543.
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 = 86643229627185/(1x4543)
LCM = 86643229627185/4543
LCM = 19071809295
Thus, we can understand that the LCM of 413,561,707,649,815 is 19071809295.
