Find LCM of 803,969,566,561,638 with Prime Factorization
| 2 | 803, 969, 566, 561, 638 |
| 3 | 803, 969, 283, 561, 319 |
| 11 | 803, 323, 283, 187, 319 |
| 17 | 73, 323, 283, 17, 29 |
| 73, 19, 283, 1, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 17 x 73 x 19 x 283 x 1 x 29 = 12771848298
Therefore, the lowest common multiple of 803,969,566,561,638 is 12771848298.
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.
803 x 969 x 566 x 561 x 638 = 157630151693916
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.
803 : 1, 11, 73, 803
969 : 1, 3, 17, 19, 51, 57, 323, 969
566 : 1, 2, 283, 566
561 : 1, 3, 11, 17, 33, 51, 187, 561
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 803,969,566,561,638, is 1.
Now, the common factors can be found like this.
803:11x 73
969:3x 17x 19
566:2x 283
561:3x 11x 17
638:2x 11x 29
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 11x 11x 17 = 12342
Therefore, the value for common factors is 12342.
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 = 157630151693916/(1x12342)
LCM = 157630151693916/12342
LCM = 12771848298
Thus, we can understand that the LCM of 803,969,566,561,638 is 12771848298.
