Given numbers are 891,871,221,662,195
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 891,871,221,662,195 is 43668952470.
Find LCM of 891,871,221,662,195 with Prime Factorization
| 3 | 891, 871, 221, 662, 195 |
| 13 | 297, 871, 221, 662, 65 |
| 297, 67, 17, 662, 5 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 297 x 67 x 17 x 662 x 5 = 43668952470
Therefore, the lowest common multiple of 891,871,221,662,195 is 43668952470.
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.
891 x 871 x 221 x 662 x 195 = 22140158902290
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.
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
871 : 1, 13, 67, 871
221 : 1, 13, 17, 221
662 : 1, 2, 331, 662
195 : 1, 3, 5, 13, 15, 39, 65, 195
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 891,871,221,662,195, is 1.
Now, the common factors can be found like this.
891:3x 3x 3x 3x 11
871:13x 67
221:13x 17
662:2x 331
195:3x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13x 13 = 507
Therefore, the value for common factors is 507.
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 = 22140158902290/(1x507)
LCM = 22140158902290/507
LCM = 43668952470
Thus, we can understand that the LCM of 891,871,221,662,195 is 43668952470.
