Find LCM of 319,170,115,990,714 with Prime Factorization
| 2 | 319, 170, 115, 990, 714 |
| 3 | 319, 85, 115, 495, 357 |
| 5 | 319, 85, 115, 165, 119 |
| 11 | 319, 17, 23, 33, 119 |
| 17 | 29, 17, 23, 3, 119 |
| 29, 1, 23, 3, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 17 x 29 x 1 x 23 x 3 x 7 = 78579270
Therefore, the lowest common multiple of 319,170,115,990,714 is 78579270.
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.
319 x 170 x 115 x 990 x 714 = 4408297047000
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.
319 : 1, 11, 29, 319
170 : 1, 2, 5, 10, 17, 34, 85, 170
115 : 1, 5, 23, 115
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 319,170,115,990,714, is 1.
Now, the common factors can be found like this.
319:11x 29
170:2x 5x 17
115:5x 23
990:2x 3x 3x 5x 11
714:2x 3x 7x 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 3x 5x 5x 11x 17 = 56100
Therefore, the value for common factors is 56100.
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 = 4408297047000/(1x56100)
LCM = 4408297047000/56100
LCM = 78579270
Thus, we can understand that the LCM of 319,170,115,990,714 is 78579270.
