Given numbers are 660,990,451,804
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 660,990,451,804 is 5439060.
Find LCM of 660,990,451,804 with Prime Factorization
| 2 | 660, 990, 451, 804 |
| 2 | 330, 495, 451, 402 |
| 3 | 165, 495, 451, 201 |
| 5 | 55, 165, 451, 67 |
| 11 | 11, 33, 451, 67 |
| 1, 3, 41, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 11 x 1 x 3 x 41 x 67 = 5439060
Therefore, the lowest common multiple of 660,990,451,804 is 5439060.
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.
660 x 990 x 451 x 804 = 236925453600
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.
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
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
451 : 1, 11, 41, 451
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,990,451,804, is 1.
Now, the common factors can be found like this.
660:2x 2x 3x 5x 11
990:2x 3x 3x 5x 11
451:11x 41
804:2x 2x 3x 67
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 3x 3x 5x 11x 11 = 43560
Therefore, the value for common factors is 43560.
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 = 236925453600/(1x43560)
LCM = 236925453600/43560
LCM = 5439060
Thus, we can understand that the LCM of 660,990,451,804 is 5439060.
