Given numbers are 297,891,400,393,235
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 297,891,400,393,235 is 2194354800.
Find LCM of 297,891,400,393,235 with Prime Factorization
| 3 | 297, 891, 400, 393, 235 |
| 3 | 99, 297, 400, 131, 235 |
| 3 | 33, 99, 400, 131, 235 |
| 5 | 11, 33, 400, 131, 235 |
| 11 | 11, 33, 80, 131, 47 |
| 1, 3, 80, 131, 47 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 5 x 11 x 1 x 3 x 80 x 131 x 47 = 2194354800
Therefore, the lowest common multiple of 297,891,400,393,235 is 2194354800.
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.
297 x 891 x 400 x 393 x 235 = 9775850634000
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.
297 : 1, 3, 9, 11, 27, 33, 99, 297
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
393 : 1, 3, 131, 393
235 : 1, 5, 47, 235
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 297,891,400,393,235, is 1.
Now, the common factors can be found like this.
297:3x 3x 3x 11
891:3x 3x 3x 3x 11
400:2x 2x 2x 2x 5x 5
393:3x 131
235:5x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 5x 11 = 4455
Therefore, the value for common factors is 4455.
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 = 9775850634000/(1x4455)
LCM = 9775850634000/4455
LCM = 2194354800
Thus, we can understand that the LCM of 297,891,400,393,235 is 2194354800.
