Find LCM of 557,878,343,954,686 with Prime Factorization
| 2 | 557, 878, 343, 954, 686 |
| 7 | 557, 439, 343, 477, 343 |
| 7 | 557, 439, 49, 477, 49 |
| 7 | 557, 439, 7, 477, 7 |
| 557, 439, 1, 477, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 7 x 7 x 557 x 439 x 1 x 477 x 1 = 80013305106
Therefore, the lowest common multiple of 557,878,343,954,686 is 80013305106.
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.
557 x 878 x 343 x 954 x 686 = 109778254605432
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.
557 : 1, 557
878 : 1, 2, 439, 878
343 : 1, 7, 49, 343
954 : 1, 2, 3, 6, 9, 18, 53, 106, 159, 318, 477, 954
686 : 1, 2, 7, 14, 49, 98, 343, 686
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 557,878,343,954,686, is 1.
Now, the common factors can be found like this.
557:557
878:2x 439
343:7x 7x 7
954:2x 3x 3x 53
686:2x 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 7x 7x 7 = 1372
Therefore, the value for common factors is 1372.
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 = 109778254605432/(1x1372)
LCM = 109778254605432/1372
LCM = 80013305106
Thus, we can understand that the LCM of 557,878,343,954,686 is 80013305106.
