Given numbers are 613,213,923,287
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 613,213,923,287 is 487152939.
Find LCM of 613,213,923,287 with Prime Factorization
| 71 | 613, 213, 923, 287 |
| 613, 3, 13, 287 |
Multiply the prime numbers at the bottom and the left side.
71 x 613 x 3 x 13 x 287 = 487152939
Therefore, the lowest common multiple of 613,213,923,287 is 487152939.
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.
613 x 213 x 923 x 287 = 34587858669
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.
613 : 1, 613
213 : 1, 3, 71, 213
923 : 1, 13, 71, 923
287 : 1, 7, 41, 287
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 613,213,923,287, is 1.
Now, the common factors can be found like this.
613:613
213:3x 71
923:13x 71
287:7x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
71 = 71
Therefore, the value for common factors is 71.
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 = 34587858669/(1x71)
LCM = 34587858669/71
LCM = 487152939
Thus, we can understand that the LCM of 613,213,923,287 is 487152939.
