Given numbers are 759,731,345,145
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 759,731,345,145 is 80450205.
Find LCM of 759,731,345,145 with Prime Factorization
| 3 | 759, 731, 345, 145 |
| 5 | 253, 731, 115, 145 |
| 23 | 253, 731, 23, 29 |
| 11, 731, 1, 29 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 23 x 11 x 731 x 1 x 29 = 80450205
Therefore, the lowest common multiple of 759,731,345,145 is 80450205.
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.
759 x 731 x 345 x 145 = 27755320725
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.
759 : 1, 3, 11, 23, 33, 69, 253, 759
731 : 1, 17, 43, 731
345 : 1, 3, 5, 15, 23, 69, 115, 345
145 : 1, 5, 29, 145
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 759,731,345,145, is 1.
Now, the common factors can be found like this.
759:3x 11x 23
731:17x 43
345:3x 5x 23
145:5x 29
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 23 = 345
Therefore, the value for common factors is 345.
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 = 27755320725/(1x345)
LCM = 27755320725/345
LCM = 80450205
Thus, we can understand that the LCM of 759,731,345,145 is 80450205.
