Given numbers are 10,891,442
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 10,891,442 is 1969110.
Find LCM of 10,891,442 with Prime Factorization
| 2 | 10, 891, 442 |
| 5, 891, 221 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 891 x 221 = 1969110
Therefore, the lowest common multiple of 10,891,442 is 1969110.
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.
10 x 891 x 442 = 3938220
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.
10 : 1, 2, 5, 10
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
442 : 1, 2, 13, 17, 26, 34, 221, 442
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 10,891,442, is 1.
Now, the common factors can be found like this.
10:2x 5
891:3x 3x 3x 3x 11
442:2x 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.
2 = 2
Therefore, the value for common factors is 2.
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 = 3938220/(1x2)
LCM = 3938220/2
LCM = 1969110
Thus, we can understand that the LCM of 10,891,442 is 1969110.
