Given numbers are 731,939,867,723
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 731,939,867,723 is 2812217673.
Find LCM of 731,939,867,723 with Prime Factorization
| 3 | 731, 939, 867, 723 |
| 17 | 731, 313, 289, 241 |
| 43, 313, 17, 241 |
Multiply the prime numbers at the bottom and the left side.
3 x 17 x 43 x 313 x 17 x 241 = 2812217673
Therefore, the lowest common multiple of 731,939,867,723 is 2812217673.
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 939 x 867 x 723 = 430269303969
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
939 : 1, 3, 313, 939
867 : 1, 3, 17, 51, 289, 867
723 : 1, 3, 241, 723
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,939,867,723, is 1.
Now, the common factors can be found like this.
731:17x 43
939:3x 313
867:3x 17x 17
723:3x 241
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 17 = 153
Therefore, the value for common factors is 153.
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 = 430269303969/(1x153)
LCM = 430269303969/153
LCM = 2812217673
Thus, we can understand that the LCM of 731,939,867,723 is 2812217673.
