Given numbers are 643,995,387,825,330
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 643,995,387,825,330 is 27235647450.
Find LCM of 643,995,387,825,330 with Prime Factorization
| 3 | 643, 995, 387, 825, 330 |
| 5 | 643, 995, 129, 275, 110 |
| 11 | 643, 199, 129, 55, 22 |
| 643, 199, 129, 5, 2 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 643 x 199 x 129 x 5 x 2 = 27235647450
Therefore, the lowest common multiple of 643,995,387,825,330 is 27235647450.
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 995 x 387 x 825 x 330 = 67408227438750
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
995 : 1, 5, 199, 995
387 : 1, 3, 9, 43, 129, 387
825 : 1, 3, 5, 11, 15, 25, 33, 55, 75, 165, 275, 825
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,995,387,825,330, is 1.
Now, the common factors can be found like this.
643:643
995:5x 199
387:3x 3x 43
825:3x 5x 5x 11
330:2x 3x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 5x 11 = 2475
Therefore, the value for common factors is 2475.
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 = 67408227438750/(1x2475)
LCM = 67408227438750/2475
LCM = 27235647450
Thus, we can understand that the LCM of 643,995,387,825,330 is 27235647450.
