Given numbers are 643,194,205,873
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 643,194,205,873 is 230148990.
Find LCM of 643,194,205,873 with Prime Factorization
97 | 643, 194, 205, 873 |
643, 2, 205, 9 |
Multiply the prime numbers at the bottom and the left side.
97 x 643 x 2 x 205 x 9 = 230148990
Therefore, the lowest common multiple of 643,194,205,873 is 230148990.
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.
643 x 194 x 205 x 873 = 22324452030
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.
643 : 1, 643
194 : 1, 2, 97, 194
205 : 1, 5, 41, 205
873 : 1, 3, 9, 97, 291, 873
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,194,205,873, is 1.
Now, the common factors can be found like this.
643:643
194:2x 97
205:5x 41
873:3x 3x 97
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
97 = 97
Therefore, the value for common factors is 97.
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 = 22324452030/(1x97)
LCM = 22324452030/97
LCM = 230148990
Thus, we can understand that the LCM of 643,194,205,873 is 230148990.
