Given numbers are 731,615,585,353,247
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 731,615,585,353,247 is 117594065745.
Find LCM of 731,615,585,353,247 with Prime Factorization
| 3 | 731, 615, 585, 353, 247 |
| 5 | 731, 205, 195, 353, 247 |
| 13 | 731, 41, 39, 353, 247 |
| 731, 41, 3, 353, 19 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 13 x 731 x 41 x 3 x 353 x 19 = 117594065745
Therefore, the lowest common multiple of 731,615,585,353,247 is 117594065745.
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 615 x 585 x 353 x 247 = 22930842820275
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
615 : 1, 3, 5, 15, 41, 123, 205, 615
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
353 : 1, 353
247 : 1, 13, 19, 247
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,615,585,353,247, is 1.
Now, the common factors can be found like this.
731:17x 43
615:3x 5x 41
585:3x 3x 5x 13
353:353
247:13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 13 = 195
Therefore, the value for common factors is 195.
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 = 22930842820275/(1x195)
LCM = 22930842820275/195
LCM = 117594065745
Thus, we can understand that the LCM of 731,615,585,353,247 is 117594065745.
