Given numbers are 309,956,480,135
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 309,956,480,135 is 106345440.
Find LCM of 309,956,480,135 with Prime Factorization
| 2 | 309, 956, 480, 135 |
| 2 | 309, 478, 240, 135 |
| 3 | 309, 239, 120, 135 |
| 5 | 103, 239, 40, 45 |
| 103, 239, 8, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 103 x 239 x 8 x 9 = 106345440
Therefore, the lowest common multiple of 309,956,480,135 is 106345440.
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.
309 x 956 x 480 x 135 = 19142179200
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.
309 : 1, 3, 103, 309
956 : 1, 2, 4, 239, 478, 956
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
135 : 1, 3, 5, 9, 15, 27, 45, 135
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 309,956,480,135, is 1.
Now, the common factors can be found like this.
309:3x 103
956:2x 2x 239
480:2x 2x 2x 2x 2x 3x 5
135:3x 3x 3x 5
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 3x 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 19142179200/(1x180)
LCM = 19142179200/180
LCM = 106345440
Thus, we can understand that the LCM of 309,956,480,135 is 106345440.
