Given numbers are 880,880,891,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 880,880,891,221 is 15752880.
Find LCM of 880,880,891,221 with Prime Factorization
| 2 | 880, 880, 891, 221 |
| 2 | 440, 440, 891, 221 |
| 2 | 220, 220, 891, 221 |
| 2 | 110, 110, 891, 221 |
| 5 | 55, 55, 891, 221 |
| 11 | 11, 11, 891, 221 |
| 1, 1, 81, 221 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 11 x 1 x 1 x 81 x 221 = 15752880
Therefore, the lowest common multiple of 880,880,891,221 is 15752880.
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.
880 x 880 x 891 x 221 = 152487878400
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.
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 880,880,891,221, is 1.
Now, the common factors can be found like this.
880:2x 2x 2x 2x 5x 11
880:2x 2x 2x 2x 5x 11
891:3x 3x 3x 3x 11
221:13x 17
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 2x 2x 5x 11x 11 = 9680
Therefore, the value for common factors is 9680.
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 = 152487878400/(1x9680)
LCM = 152487878400/9680
LCM = 15752880
Thus, we can understand that the LCM of 880,880,891,221 is 15752880.
