Find LCM of 855,670,171,450,394 with Prime Factorization
| 2 | 855, 670, 171, 450, 394 |
| 3 | 855, 335, 171, 225, 197 |
| 3 | 285, 335, 57, 75, 197 |
| 5 | 95, 335, 19, 25, 197 |
| 19 | 19, 67, 19, 5, 197 |
| 1, 67, 1, 5, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 19 x 1 x 67 x 1 x 5 x 197 = 112851450
Therefore, the lowest common multiple of 855,670,171,450,394 is 112851450.
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.
855 x 670 x 171 x 450 x 394 = 17367838155000
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.
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
670 : 1, 2, 5, 10, 67, 134, 335, 670
171 : 1, 3, 9, 19, 57, 171
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
394 : 1, 2, 197, 394
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,670,171,450,394, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
670:2x 5x 67
171:3x 3x 19
450:2x 3x 3x 5x 5
394:2x 197
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 3x 3x 5x 5x 19 = 153900
Therefore, the value for common factors is 153900.
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 = 17367838155000/(1x153900)
LCM = 17367838155000/153900
LCM = 112851450
Thus, we can understand that the LCM of 855,670,171,450,394 is 112851450.
