The LCM of 261,771,754,858,976 is 9361802736.
Find LCM of 261,771,754,858,976 with Prime Factorization
| 2 | 261, 771, 754, 858, 976 |
| 3 | 261, 771, 377, 429, 488 |
| 13 | 87, 257, 377, 143, 488 |
| 29 | 87, 257, 29, 11, 488 |
| 3, 257, 1, 11, 488 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 29 x 3 x 257 x 1 x 11 x 488 = 9361802736
Therefore, the lowest common multiple of 261,771,754,858,976 is 9361802736.
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.
261 x 771 x 754 x 858 x 976 = 127058386732992
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.
261 : 1, 3, 9, 29, 87, 261
771 : 1, 3, 257, 771
754 : 1, 2, 13, 26, 29, 58, 377, 754
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 261,771,754,858,976, is 1.
Now, the common factors can be found like this.
261:3x 3x 29
771:3x 257
754:2x 13x 29
858:2x 3x 11x 13
976:2x 2x 2x 2x 61
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 3x 3x 13x 29 = 13572
Therefore, the value for common factors is 13572.
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 = 127058386732992/(1x13572)
LCM = 127058386732992/13572
LCM = 9361802736
Thus, we can understand that the LCM of 261,771,754,858,976 is 9361802736.
