Given numbers are 986,338,715,898,878
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 986,338,715,898,878 is 1806496690570.
Find LCM of 986,338,715,898,878 with Prime Factorization
| 2 | 986, 338, 715, 898, 878 |
| 13 | 493, 169, 715, 449, 439 |
| 493, 13, 55, 449, 439 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 493 x 13 x 55 x 449 x 439 = 1806496690570
Therefore, the lowest common multiple of 986,338,715,898,878 is 1806496690570.
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.
986 x 338 x 715 x 898 x 878 = 187875655819280
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.
986 : 1, 2, 17, 29, 34, 58, 493, 986
338 : 1, 2, 13, 26, 169, 338
715 : 1, 5, 11, 13, 55, 65, 143, 715
898 : 1, 2, 449, 898
878 : 1, 2, 439, 878
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 986,338,715,898,878, is 1.
Now, the common factors can be found like this.
986:2x 17x 29
338:2x 13x 13
715:5x 11x 13
898:2x 449
878:2x 439
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 2x 13 = 104
Therefore, the value for common factors is 104.
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 = 187875655819280/(1x104)
LCM = 187875655819280/104
LCM = 1806496690570
Thus, we can understand that the LCM of 986,338,715,898,878 is 1806496690570.
