Find LCM of 811,686,231,771,550 with Prime Factorization
| 2 | 811, 686, 231, 771, 550 |
| 3 | 811, 343, 231, 771, 275 |
| 7 | 811, 343, 77, 257, 275 |
| 11 | 811, 49, 11, 257, 275 |
| 811, 49, 1, 257, 25 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 11 x 811 x 49 x 1 x 257 x 25 = 117959260650
Therefore, the lowest common multiple of 811,686,231,771,550 is 117959260650.
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 686 x 231 x 771 x 550 = 54497178420300
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
686 : 1, 2, 7, 14, 49, 98, 343, 686
231 : 1, 3, 7, 11, 21, 33, 77, 231
771 : 1, 3, 257, 771
550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 811,686,231,771,550, is 1.
Now, the common factors can be found like this.
811:811
686:2x 7x 7x 7
231:3x 7x 11
771:3x 257
550:2x 5x 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 7x 11 = 462
Therefore, the value for common factors is 462.
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 = 54497178420300/(1x462)
LCM = 54497178420300/462
LCM = 117959260650
Thus, we can understand that the LCM of 811,686,231,771,550 is 117959260650.
