The LCM of 811,51,765,261 is 17992035.
Find LCM of 811,51,765,261 with Prime Factorization
| 3 | 811, 51, 765, 261 |
| 3 | 811, 17, 255, 87 |
| 17 | 811, 17, 85, 29 |
| 811, 1, 5, 29 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 17 x 811 x 1 x 5 x 29 = 17992035
Therefore, the lowest common multiple of 811,51,765,261 is 17992035.
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 51 x 765 x 261 = 8258344065
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
51 : 1, 3, 17, 51
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
261 : 1, 3, 9, 29, 87, 261
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 811,51,765,261, is 1.
Now, the common factors can be found like this.
811:811
51:3x 17
765:3x 3x 5x 17
261:3x 3x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 17 = 459
Therefore, the value for common factors is 459.
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 = 8258344065/(1x459)
LCM = 8258344065/459
LCM = 17992035
Thus, we can understand that the LCM of 811,51,765,261 is 17992035.
