Find LCM of 326,731,135,945 with Prime Factorization
3 | 326, 731, 135, 945 |
3 | 326, 731, 45, 315 |
3 | 326, 731, 15, 105 |
5 | 326, 731, 5, 35 |
326, 731, 1, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 5 x 326 x 731 x 1 x 7 = 225199170
Therefore, the lowest common multiple of 326,731,135,945 is 225199170.
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.
326 x 731 x 135 x 945 = 30401887950
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.
326 : 1, 2, 163, 326
731 : 1, 17, 43, 731
135 : 1, 3, 5, 9, 15, 27, 45, 135
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 326,731,135,945, is 1.
Now, the common factors can be found like this.
326:2x 163
731:17x 43
135:3x 3x 3x 5
945:3x 3x 3x 5x 7
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 3x 5 = 135
Therefore, the value for common factors is 135.
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 = 30401887950/(1x135)
LCM = 30401887950/135
LCM = 225199170
Thus, we can understand that the LCM of 326,731,135,945 is 225199170.
