Find LCM of 561,884,715,682 with Prime Factorization
| 2 | 561, 884, 715, 682 |
| 11 | 561, 442, 715, 341 |
| 13 | 51, 442, 65, 31 |
| 17 | 51, 34, 5, 31 |
| 3, 2, 5, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 13 x 17 x 3 x 2 x 5 x 31 = 4521660
Therefore, the lowest common multiple of 561,884,715,682 is 4521660.
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.
561 x 884 x 715 x 682 = 241827420120
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.
561 : 1, 3, 11, 17, 33, 51, 187, 561
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
715 : 1, 5, 11, 13, 55, 65, 143, 715
682 : 1, 2, 11, 22, 31, 62, 341, 682
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,884,715,682, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
884:2x 2x 13x 17
715:5x 11x 13
682:2x 11x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 11x 13x 17 = 53482
Therefore, the value for common factors is 53482.
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 = 241827420120/(1x53482)
LCM = 241827420120/53482
LCM = 4521660
Thus, we can understand that the LCM of 561,884,715,682 is 4521660.
