Given numbers are 731,195,507,261,731
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 731,195,507,261,731 is 161218395.
Find LCM of 731,195,507,261,731 with Prime Factorization
| 3 | 731, 195, 507, 261, 731 |
| 13 | 731, 65, 169, 87, 731 |
| 17 | 731, 5, 13, 87, 731 |
| 43 | 43, 5, 13, 87, 43 |
| 1, 5, 13, 87, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 17 x 43 x 1 x 5 x 13 x 87 x 1 = 161218395
Therefore, the lowest common multiple of 731,195,507,261,731 is 161218395.
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.
731 x 195 x 507 x 261 x 731 = 13788525669165
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.
731 : 1, 17, 43, 731
195 : 1, 3, 5, 13, 15, 39, 65, 195
507 : 1, 3, 13, 39, 169, 507
261 : 1, 3, 9, 29, 87, 261
731 : 1, 17, 43, 731
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,195,507,261,731, is 1.
Now, the common factors can be found like this.
731:17x 43
195:3x 5x 13
507:3x 13x 13
261:3x 3x 29
731:17x 43
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 13x 17x 43 = 85527
Therefore, the value for common factors is 85527.
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 = 13788525669165/(1x85527)
LCM = 13788525669165/85527
LCM = 161218395
Thus, we can understand that the LCM of 731,195,507,261,731 is 161218395.
