Given numbers are 898,998,802,686,197
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 898,998,802,686,197 is 12141758797042.
Find LCM of 898,998,802,686,197 with Prime Factorization
| 2 | 898, 998, 802, 686, 197 |
| 449, 499, 401, 343, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 449 x 499 x 401 x 343 x 197 = 12141758797042
Therefore, the lowest common multiple of 898,998,802,686,197 is 12141758797042.
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.
898 x 998 x 802 x 686 x 197 = 97134070376336
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.
898 : 1, 2, 449, 898
998 : 1, 2, 499, 998
802 : 1, 2, 401, 802
686 : 1, 2, 7, 14, 49, 98, 343, 686
197 : 1, 197
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 898,998,802,686,197, is 1.
Now, the common factors can be found like this.
898:2x 449
998:2x 499
802:2x 401
686:2x 7x 7x 7
197:197
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 2 = 8
Therefore, the value for common factors is 8.
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 = 97134070376336/(1x8)
LCM = 97134070376336/8
LCM = 12141758797042
Thus, we can understand that the LCM of 898,998,802,686,197 is 12141758797042.
