Given numbers are 198,945,946,731
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 198,945,946,731 is 15197490.
Find LCM of 198,945,946,731 with Prime Factorization
| 2 | 198, 945, 946, 731 |
| 3 | 99, 945, 473, 731 |
| 3 | 33, 315, 473, 731 |
| 11 | 11, 105, 473, 731 |
| 43 | 1, 105, 43, 731 |
| 1, 105, 1, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 11 x 43 x 1 x 105 x 1 x 17 = 15197490
Therefore, the lowest common multiple of 198,945,946,731 is 15197490.
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.
198 x 945 x 946 x 731 = 129391429860
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.
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
946 : 1, 2, 11, 22, 43, 86, 473, 946
731 : 1, 17, 43, 731
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 198,945,946,731, is 1.
Now, the common factors can be found like this.
198:2x 3x 3x 11
945:3x 3x 3x 5x 7
946:2x 11x 43
731:17x 43
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 3x 11x 43 = 8514
Therefore, the value for common factors is 8514.
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 = 129391429860/(1x8514)
LCM = 129391429860/8514
LCM = 15197490
Thus, we can understand that the LCM of 198,945,946,731 is 15197490.
