Find LCM of 621,753,454,644,231 with Prime Factorization
| 2 | 621, 753, 454, 644, 231 |
| 3 | 621, 753, 227, 322, 231 |
| 7 | 207, 251, 227, 322, 77 |
| 23 | 207, 251, 227, 46, 11 |
| 9, 251, 227, 2, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 23 x 9 x 251 x 227 x 2 x 11 = 10897876836
Therefore, the lowest common multiple of 621,753,454,644,231 is 10897876836.
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 753 x 454 x 644 x 231 = 31582047070728
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
753 : 1, 3, 251, 753
454 : 1, 2, 227, 454
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
231 : 1, 3, 7, 11, 21, 33, 77, 231
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,753,454,644,231, is 1.
Now, the common factors can be found like this.
621:3x 3x 3x 23
753:3x 251
454:2x 227
644:2x 2x 7x 23
231:3x 7x 11
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 7x 23 = 2898
Therefore, the value for common factors is 2898.
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 = 31582047070728/(1x2898)
LCM = 31582047070728/2898
LCM = 10897876836
Thus, we can understand that the LCM of 621,753,454,644,231 is 10897876836.
