Find LCM of 621,687,889,228,324 with Prime Factorization
| 2 | 621, 687, 889, 228, 324 |
| 2 | 621, 687, 889, 114, 162 |
| 3 | 621, 687, 889, 57, 81 |
| 3 | 207, 229, 889, 19, 27 |
| 3 | 69, 229, 889, 19, 9 |
| 23, 229, 889, 19, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 23 x 229 x 889 x 19 x 3 = 28824626628
Therefore, the lowest common multiple of 621,687,889,228,324 is 28824626628.
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.
621 x 687 x 889 x 228 x 324 = 28017537082416
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.
621 : 1, 3, 9, 23, 27, 69, 207, 621
687 : 1, 3, 229, 687
889 : 1, 7, 127, 889
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
324 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 324
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,687,889,228,324, is 1.
Now, the common factors can be found like this.
621:3x 3x 3x 23
687:3x 229
889:7x 127
228:2x 2x 3x 19
324:2x 2x 3x 3x 3x 3
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 3 = 972
Therefore, the value for common factors is 972.
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 = 28017537082416/(1x972)
LCM = 28017537082416/972
LCM = 28824626628
Thus, we can understand that the LCM of 621,687,889,228,324 is 28824626628.
