Given numbers are 209,231,847
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 209,231,847 is 48279.
Find LCM of 209,231,847 with Prime Factorization
| 7 | 209, 231, 847 |
| 11 | 209, 33, 121 |
| 19, 3, 11 |
Multiply the prime numbers at the bottom and the left side.
7 x 11 x 19 x 3 x 11 = 48279
Therefore, the lowest common multiple of 209,231,847 is 48279.
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.
209 x 231 x 847 = 40892313
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.
209 : 1, 11, 19, 209
231 : 1, 3, 7, 11, 21, 33, 77, 231
847 : 1, 7, 11, 77, 121, 847
11 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,231,847, is 11.
Now, the common factors can be found like this.
209:11x 19
231:3x 7x 11
847:7x 11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 11 = 77
Therefore, the value for common factors is 77.
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 = 40892313/(11x77)
LCM = 40892313/847
LCM = 48279
Thus, we can understand that the LCM of 209,231,847 is 48279.
