Given numbers are 605,913,673,985,287
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 605,913,673,985,287 is 1910718260605.
Find LCM of 605,913,673,985,287 with Prime Factorization
| 5 | 605, 913, 673, 985, 287 |
| 11 | 121, 913, 673, 197, 287 |
| 11, 83, 673, 197, 287 |
Multiply the prime numbers at the bottom and the left side.
5 x 11 x 11 x 83 x 673 x 197 x 287 = 1910718260605
Therefore, the lowest common multiple of 605,913,673,985,287 is 1910718260605.
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.
605 x 913 x 673 x 985 x 287 = 105089504333275
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.
605 : 1, 5, 11, 55, 121, 605
913 : 1, 11, 83, 913
673 : 1, 673
985 : 1, 5, 197, 985
287 : 1, 7, 41, 287
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,913,673,985,287, is 1.
Now, the common factors can be found like this.
605:5x 11x 11
913:11x 83
673:673
985:5x 197
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.
5x 11 = 55
Therefore, the value for common factors is 55.
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 = 105089504333275/(1x55)
LCM = 105089504333275/55
LCM = 1910718260605
Thus, we can understand that the LCM of 605,913,673,985,287 is 1910718260605.
