Given numbers are 814,198,111,905
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 814,198,111,905 is 6630030.
Find LCM of 814,198,111,905 with Prime Factorization
| 2 | 814, 198, 111, 905 |
| 3 | 407, 99, 111, 905 |
| 11 | 407, 33, 37, 905 |
| 37 | 37, 3, 37, 905 |
| 1, 3, 1, 905 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 37 x 1 x 3 x 1 x 905 = 6630030
Therefore, the lowest common multiple of 814,198,111,905 is 6630030.
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.
814 x 198 x 111 x 905 = 16190533260
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.
814 : 1, 2, 11, 22, 37, 74, 407, 814
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
111 : 1, 3, 37, 111
905 : 1, 5, 181, 905
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 814,198,111,905, is 1.
Now, the common factors can be found like this.
814:2x 11x 37
198:2x 3x 3x 11
111:3x 37
905:5x 181
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 11x 37 = 2442
Therefore, the value for common factors is 2442.
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 = 16190533260/(1x2442)
LCM = 16190533260/2442
LCM = 6630030
Thus, we can understand that the LCM of 814,198,111,905 is 6630030.
