Given numbers are 943,405,642,989,844
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 943,405,642,989,844 is 1483069132260.
Find LCM of 943,405,642,989,844 with Prime Factorization
| 2 | 943, 405, 642, 989, 844 |
| 3 | 943, 405, 321, 989, 422 |
| 23 | 943, 135, 107, 989, 422 |
| 41, 135, 107, 43, 422 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 41 x 135 x 107 x 43 x 422 = 1483069132260
Therefore, the lowest common multiple of 943,405,642,989,844 is 1483069132260.
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.
943 x 405 x 642 x 989 x 844 = 204663540251880
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.
943 : 1, 23, 41, 943
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
642 : 1, 2, 3, 6, 107, 214, 321, 642
989 : 1, 23, 43, 989
844 : 1, 2, 4, 211, 422, 844
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 943,405,642,989,844, is 1.
Now, the common factors can be found like this.
943:23x 41
405:3x 3x 3x 3x 5
642:2x 3x 107
989:23x 43
844:2x 2x 211
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 23 = 138
Therefore, the value for common factors is 138.
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 = 204663540251880/(1x138)
LCM = 204663540251880/138
LCM = 1483069132260
Thus, we can understand that the LCM of 943,405,642,989,844 is 1483069132260.
