Find LCM of 808,649,528,621 with Prime Factorization
| 2 | 808, 649, 528, 621 |
| 2 | 404, 649, 264, 621 |
| 2 | 202, 649, 132, 621 |
| 3 | 101, 649, 66, 621 |
| 11 | 101, 649, 22, 207 |
| 101, 59, 2, 207 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 11 x 101 x 59 x 2 x 207 = 651294864
Therefore, the lowest common multiple of 808,649,528,621 is 651294864.
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.
808 x 649 x 528 x 621 = 171941844096
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.
808 : 1, 2, 4, 8, 101, 202, 404, 808
649 : 1, 11, 59, 649
528 : 1, 2, 3, 4, 6, 8, 11, 12, 16, 22, 24, 33, 44, 48, 66, 88, 132, 176, 264, 528
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 808,649,528,621, is 1.
Now, the common factors can be found like this.
808:2x 2x 2x 101
649:11x 59
528:2x 2x 2x 2x 3x 11
621:3x 3x 3x 23
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 2x 3x 11 = 264
Therefore, the value for common factors is 264.
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 = 171941844096/(1x264)
LCM = 171941844096/264
LCM = 651294864
Thus, we can understand that the LCM of 808,649,528,621 is 651294864.
