Given numbers are 814,561,484,603,321
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 814,561,484,603,321 is 19642515156.
Find LCM of 814,561,484,603,321 with Prime Factorization
| 2 | 814, 561, 484, 603, 321 |
| 3 | 407, 561, 242, 603, 321 |
| 11 | 407, 187, 242, 201, 107 |
| 37, 17, 22, 201, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 37 x 17 x 22 x 201 x 107 = 19642515156
Therefore, the lowest common multiple of 814,561,484,603,321 is 19642515156.
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.
814 x 561 x 484 x 603 x 321 = 42781398009768
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.
814 : 1, 2, 11, 22, 37, 74, 407, 814
561 : 1, 3, 11, 17, 33, 51, 187, 561
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
603 : 1, 3, 9, 67, 201, 603
321 : 1, 3, 107, 321
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 814,561,484,603,321, is 1.
Now, the common factors can be found like this.
814:2x 11x 37
561:3x 11x 17
484:2x 2x 11x 11
603:3x 3x 67
321:3x 107
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 11x 11 = 2178
Therefore, the value for common factors is 2178.
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 = 42781398009768/(1x2178)
LCM = 42781398009768/2178
LCM = 19642515156
Thus, we can understand that the LCM of 814,561,484,603,321 is 19642515156.
