Find LCM of 448,405,308,132 with Prime Factorization
| 2 | 448, 405, 308, 132 |
| 2 | 224, 405, 154, 66 |
| 3 | 112, 405, 77, 33 |
| 7 | 112, 135, 77, 11 |
| 11 | 16, 135, 11, 11 |
| 16, 135, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 11 x 16 x 135 x 1 x 1 = 1995840
Therefore, the lowest common multiple of 448,405,308,132 is 1995840.
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.
448 x 405 x 308 x 132 = 7376624640
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.
448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
132 : 1, 2, 3, 4, 6, 11, 12, 22, 33, 44, 66, 132
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 448,405,308,132, is 1.
Now, the common factors can be found like this.
448:2x 2x 2x 2x 2x 2x 7
405:3x 3x 3x 3x 5
308:2x 2x 7x 11
132:2x 2x 3x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 3x 7x 11 = 3696
Therefore, the value for common factors is 3696.
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 = 7376624640/(1x3696)
LCM = 7376624640/3696
LCM = 1995840
Thus, we can understand that the LCM of 448,405,308,132 is 1995840.
