Find LCM of 648,939,215,828,645 with Prime Factorization
| 2 | 648, 939, 215, 828, 645 |
| 2 | 324, 939, 215, 414, 645 |
| 3 | 162, 939, 215, 207, 645 |
| 3 | 54, 313, 215, 69, 215 |
| 5 | 18, 313, 215, 23, 215 |
| 43 | 18, 313, 43, 23, 43 |
| 18, 313, 1, 23, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 43 x 18 x 313 x 1 x 23 x 1 = 1002964680
Therefore, the lowest common multiple of 648,939,215,828,645 is 1002964680.
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.
648 x 939 x 215 x 828 x 645 = 69866519608800
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.
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
939 : 1, 3, 313, 939
215 : 1, 5, 43, 215
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
645 : 1, 3, 5, 15, 43, 129, 215, 645
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 648,939,215,828,645, is 1.
Now, the common factors can be found like this.
648:2x 2x 2x 3x 3x 3x 3
939:3x 313
215:5x 43
828:2x 2x 3x 3x 23
645:3x 5x 43
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 43 = 69660
Therefore, the value for common factors is 69660.
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 = 69866519608800/(1x69660)
LCM = 69866519608800/69660
LCM = 1002964680
Thus, we can understand that the LCM of 648,939,215,828,645 is 1002964680.
