Given numbers are 832,842,646,731,427
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 832,842,646,731,427 is 2077324174016.
Find LCM of 832,842,646,731,427 with Prime Factorization
| 2 | 832, 842, 646, 731, 427 |
| 17 | 416, 421, 323, 731, 427 |
| 416, 421, 19, 43, 427 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 416 x 421 x 19 x 43 x 427 = 2077324174016
Therefore, the lowest common multiple of 832,842,646,731,427 is 2077324174016.
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.
832 x 842 x 646 x 731 x 427 = 141258043833088
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.
832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832
842 : 1, 2, 421, 842
646 : 1, 2, 17, 19, 34, 38, 323, 646
731 : 1, 17, 43, 731
427 : 1, 7, 61, 427
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 832,842,646,731,427, is 1.
Now, the common factors can be found like this.
832:2x 2x 2x 2x 2x 2x 13
842:2x 421
646:2x 17x 19
731:17x 43
427:7x 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 17 = 68
Therefore, the value for common factors is 68.
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 = 141258043833088/(1x68)
LCM = 141258043833088/68
LCM = 2077324174016
Thus, we can understand that the LCM of 832,842,646,731,427 is 2077324174016.
