The LCM of 582,561,945,418 is 651371490.
Find LCM of 582,561,945,418 with Prime Factorization
| 2 | 582, 561, 945, 418 |
| 3 | 291, 561, 945, 209 |
| 11 | 97, 187, 315, 209 |
| 97, 17, 315, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 97 x 17 x 315 x 19 = 651371490
Therefore, the lowest common multiple of 582,561,945,418 is 651371490.
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.
582 x 561 x 945 x 418 = 128971555020
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.
582 : 1, 2, 3, 6, 97, 194, 291, 582
561 : 1, 3, 11, 17, 33, 51, 187, 561
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
418 : 1, 2, 11, 19, 22, 38, 209, 418
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 582,561,945,418, is 1.
Now, the common factors can be found like this.
582:2x 3x 97
561:3x 11x 17
945:3x 3x 3x 5x 7
418:2x 11x 19
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 11 = 198
Therefore, the value for common factors is 198.
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 = 128971555020/(1x198)
LCM = 128971555020/198
LCM = 651371490
Thus, we can understand that the LCM of 582,561,945,418 is 651371490.
