Given numbers are 729,851,920,699,285
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 729,851,920,699,285 is 109856713320.
Find LCM of 729,851,920,699,285 with Prime Factorization
| 3 | 729, 851, 920, 699, 285 |
| 5 | 243, 851, 920, 233, 95 |
| 23 | 243, 851, 184, 233, 19 |
| 243, 37, 8, 233, 19 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 23 x 243 x 37 x 8 x 233 x 19 = 109856713320
Therefore, the lowest common multiple of 729,851,920,699,285 is 109856713320.
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.
729 x 851 x 920 x 699 x 285 = 113701698286200
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.
729 : 1, 3, 9, 27, 81, 243, 729
851 : 1, 23, 37, 851
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
699 : 1, 3, 233, 699
285 : 1, 3, 5, 15, 19, 57, 95, 285
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 729,851,920,699,285, is 1.
Now, the common factors can be found like this.
729:3x 3x 3x 3x 3x 3
851:23x 37
920:2x 2x 2x 5x 23
699:3x 233
285:3x 5x 19
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 23 = 1035
Therefore, the value for common factors is 1035.
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 = 113701698286200/(1x1035)
LCM = 113701698286200/1035
LCM = 109856713320
Thus, we can understand that the LCM of 729,851,920,699,285 is 109856713320.
