The LCM of 428,135,867,270 is 16698420.
Find LCM of 428,135,867,270 with Prime Factorization
| 2 | 428, 135, 867, 270 |
| 3 | 214, 135, 867, 135 |
| 3 | 214, 45, 289, 45 |
| 3 | 214, 15, 289, 15 |
| 5 | 214, 5, 289, 5 |
| 214, 1, 289, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 5 x 214 x 1 x 289 x 1 = 16698420
Therefore, the lowest common multiple of 428,135,867,270 is 16698420.
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.
428 x 135 x 867 x 270 = 13525720200
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.
428 : 1, 2, 4, 107, 214, 428
135 : 1, 3, 5, 9, 15, 27, 45, 135
867 : 1, 3, 17, 51, 289, 867
270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,135,867,270, is 1.
Now, the common factors can be found like this.
428:2x 2x 107
135:3x 3x 3x 5
867:3x 17x 17
270:2x 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 3x 3x 3x 3x 5 = 810
Therefore, the value for common factors is 810.
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 = 13525720200/(1x810)
LCM = 13525720200/810
LCM = 16698420
Thus, we can understand that the LCM of 428,135,867,270 is 16698420.
