The LCM of 864,170,309,612 is 7564320.
Find LCM of 864,170,309,612 with Prime Factorization
| 2 | 864, 170, 309, 612 |
| 2 | 432, 85, 309, 306 |
| 3 | 216, 85, 309, 153 |
| 3 | 72, 85, 103, 51 |
| 17 | 24, 85, 103, 17 |
| 24, 5, 103, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 17 x 24 x 5 x 103 x 1 = 7564320
Therefore, the lowest common multiple of 864,170,309,612 is 7564320.
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.
864 x 170 x 309 x 612 = 27776183040
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.
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
170 : 1, 2, 5, 10, 17, 34, 85, 170
309 : 1, 3, 103, 309
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 864,170,309,612, is 1.
Now, the common factors can be found like this.
864:2x 2x 2x 2x 2x 3x 3x 3
170:2x 5x 17
309:3x 103
612:2x 2x 3x 3x 17
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 3x 3x 3x 17 = 3672
Therefore, the value for common factors is 3672.
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 = 27776183040/(1x3672)
LCM = 27776183040/3672
LCM = 7564320
Thus, we can understand that the LCM of 864,170,309,612 is 7564320.
