Given numbers are 254,731,646,449
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 254,731,646,449 is 1583984894.
Find LCM of 254,731,646,449 with Prime Factorization
| 2 | 254, 731, 646, 449 |
| 17 | 127, 731, 323, 449 |
| 127, 43, 19, 449 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 127 x 43 x 19 x 449 = 1583984894
Therefore, the lowest common multiple of 254,731,646,449 is 1583984894.
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.
254 x 731 x 646 x 449 = 53855486396
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.
254 : 1, 2, 127, 254
731 : 1, 17, 43, 731
646 : 1, 2, 17, 19, 34, 38, 323, 646
449 : 1, 449
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 254,731,646,449, is 1.
Now, the common factors can be found like this.
254:2x 127
731:17x 43
646:2x 17x 19
449:449
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 17 = 34
Therefore, the value for common factors is 34.
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 = 53855486396/(1x34)
LCM = 53855486396/34
LCM = 1583984894
Thus, we can understand that the LCM of 254,731,646,449 is 1583984894.
