Given numbers are 825,190,803,891
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 825,190,803,891 is 61790850.
Find LCM of 825,190,803,891 with Prime Factorization
| 3 | 825, 190, 803, 891 |
| 5 | 275, 190, 803, 297 |
| 11 | 55, 38, 803, 297 |
| 5, 38, 73, 27 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 5 x 38 x 73 x 27 = 61790850
Therefore, the lowest common multiple of 825,190,803,891 is 61790850.
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.
825 x 190 x 803 x 891 = 112150392750
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.
825 : 1, 3, 5, 11, 15, 25, 33, 55, 75, 165, 275, 825
190 : 1, 2, 5, 10, 19, 38, 95, 190
803 : 1, 11, 73, 803
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 825,190,803,891, is 1.
Now, the common factors can be found like this.
825:3x 5x 5x 11
190:2x 5x 19
803:11x 73
891:3x 3x 3x 3x 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 5x 11x 11 = 1815
Therefore, the value for common factors is 1815.
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 = 112150392750/(1x1815)
LCM = 112150392750/1815
LCM = 61790850
Thus, we can understand that the LCM of 825,190,803,891 is 61790850.
