Given numbers are 193,469,231,871
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 193,469,231,871 is 38831793.
Find LCM of 193,469,231,871 with Prime Factorization
| 7 | 193, 469, 231, 871 |
| 67 | 193, 67, 33, 871 |
| 193, 1, 33, 13 |
Multiply the prime numbers at the bottom and the left side.
7 x 67 x 193 x 1 x 33 x 13 = 38831793
Therefore, the lowest common multiple of 193,469,231,871 is 38831793.
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.
193 x 469 x 231 x 871 = 18212110917
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.
193 : 1, 193
469 : 1, 7, 67, 469
231 : 1, 3, 7, 11, 21, 33, 77, 231
871 : 1, 13, 67, 871
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 193,469,231,871, is 1.
Now, the common factors can be found like this.
193:193
469:7x 67
231:3x 7x 11
871:13x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 67 = 469
Therefore, the value for common factors is 469.
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 = 18212110917/(1x469)
LCM = 18212110917/469
LCM = 38831793
Thus, we can understand that the LCM of 193,469,231,871 is 38831793.
