Find LCM of 216,391,395,990,185 with Prime Factorization
| 2 | 216, 391, 395, 990, 185 |
| 3 | 108, 391, 395, 495, 185 |
| 3 | 36, 391, 395, 165, 185 |
| 5 | 12, 391, 395, 55, 185 |
| 12, 391, 79, 11, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 12 x 391 x 79 x 11 x 37 = 13577568840
Therefore, the lowest common multiple of 216,391,395,990,185 is 13577568840.
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.
216 x 391 x 395 x 990 x 185 = 6109905978000
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.
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
391 : 1, 17, 23, 391
395 : 1, 5, 79, 395
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
185 : 1, 5, 37, 185
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 216,391,395,990,185, is 1.
Now, the common factors can be found like this.
216:2x 2x 2x 3x 3x 3
391:17x 23
395:5x 79
990:2x 3x 3x 5x 11
185:5x 37
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 5x 5 = 450
Therefore, the value for common factors is 450.
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 = 6109905978000/(1x450)
LCM = 6109905978000/450
LCM = 13577568840
Thus, we can understand that the LCM of 216,391,395,990,185 is 13577568840.
