Given numbers are 804,876,920,990
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 804,876,920,990 is 445472280.
Find LCM of 804,876,920,990 with Prime Factorization
| 2 | 804, 876, 920, 990 |
| 2 | 402, 438, 460, 495 |
| 3 | 201, 219, 230, 495 |
| 5 | 67, 73, 230, 165 |
| 67, 73, 46, 33 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 67 x 73 x 46 x 33 = 445472280
Therefore, the lowest common multiple of 804,876,920,990 is 445472280.
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.
804 x 876 x 920 x 990 = 641480083200
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.
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 804,876,920,990, is 2.
Now, the common factors can be found like this.
804:2x 2x 3x 67
876:2x 2x 3x 73
920:2x 2x 2x 5x 23
990:2x 3x 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.
2x 2x 2x 2x 3x 3x 5 = 720
Therefore, the value for common factors is 720.
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 = 641480083200/(2x720)
LCM = 641480083200/1440
LCM = 445472280
Thus, we can understand that the LCM of 804,876,920,990 is 445472280.
