Find LCM of 828,231,621,644,213 with Prime Factorization
| 2 | 828, 231, 621, 644, 213 |
| 2 | 414, 231, 621, 322, 213 |
| 3 | 207, 231, 621, 161, 213 |
| 3 | 69, 77, 207, 161, 71 |
| 7 | 23, 77, 69, 161, 71 |
| 23 | 23, 11, 69, 23, 71 |
| 1, 11, 3, 1, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 7 x 23 x 1 x 11 x 3 x 1 x 71 = 13580028
Therefore, the lowest common multiple of 828,231,621,644,213 is 13580028.
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.
828 x 231 x 621 x 644 x 213 = 16292937353616
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.
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
231 : 1, 3, 7, 11, 21, 33, 77, 231
621 : 1, 3, 9, 23, 27, 69, 207, 621
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
213 : 1, 3, 71, 213
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 828,231,621,644,213, is 1.
Now, the common factors can be found like this.
828:2x 2x 3x 3x 23
231:3x 7x 11
621:3x 3x 3x 23
644:2x 2x 7x 23
213:3x 71
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 7x 23x 23 = 1199772
Therefore, the value for common factors is 1199772.
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 = 16292937353616/(1x1199772)
LCM = 16292937353616/1199772
LCM = 13580028
Thus, we can understand that the LCM of 828,231,621,644,213 is 13580028.
