The LCM of 811,550,711,990 is 317141550.
Find LCM of 811,550,711,990 with Prime Factorization
| 2 | 811, 550, 711, 990 |
| 3 | 811, 275, 711, 495 |
| 3 | 811, 275, 237, 165 |
| 5 | 811, 275, 79, 55 |
| 11 | 811, 11, 79, 55 |
| 811, 1, 79, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 11 x 811 x 1 x 79 x 5 = 317141550
Therefore, the lowest common multiple of 811,550,711,990 is 317141550.
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.
811 x 550 x 711 x 990 = 313970134500
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.
811 : 1, 811
550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550
711 : 1, 3, 9, 79, 237, 711
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 811,550,711,990, is 1.
Now, the common factors can be found like this.
811:811
550:2x 5x 5x 11
711:3x 3x 79
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 3x 3x 5x 11 = 990
Therefore, the value for common factors is 990.
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 = 313970134500/(1x990)
LCM = 313970134500/990
LCM = 317141550
Thus, we can understand that the LCM of 811,550,711,990 is 317141550.
