Given numbers are 298,223,858,385
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 298,223,858,385 is 997806810.
Find LCM of 298,223,858,385 with Prime Factorization
| 2 | 298, 223, 858, 385 |
| 11 | 149, 223, 429, 385 |
| 149, 223, 39, 35 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 149 x 223 x 39 x 35 = 997806810
Therefore, the lowest common multiple of 298,223,858,385 is 997806810.
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.
298 x 223 x 858 x 385 = 21951749820
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.
298 : 1, 2, 149, 298
223 : 1, 223
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
385 : 1, 5, 7, 11, 35, 55, 77, 385
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 298,223,858,385, is 1.
Now, the common factors can be found like this.
298:2x 149
223:223
858:2x 3x 11x 13
385:5x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11 = 22
Therefore, the value for common factors is 22.
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 = 21951749820/(1x22)
LCM = 21951749820/22
LCM = 997806810
Thus, we can understand that the LCM of 298,223,858,385 is 997806810.
