Given numbers are 445,781,891,913
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 445,781,891,913 is 2336545035.
Find LCM of 445,781,891,913 with Prime Factorization
11 | 445, 781, 891, 913 |
445, 71, 81, 83 |
Multiply the prime numbers at the bottom and the left side.
11 x 445 x 71 x 81 x 83 = 2336545035
Therefore, the lowest common multiple of 445,781,891,913 is 2336545035.
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.
445 x 781 x 891 x 913 = 282721949235
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.
445 : 1, 5, 89, 445
781 : 1, 11, 71, 781
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
913 : 1, 11, 83, 913
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 445,781,891,913, is 1.
Now, the common factors can be found like this.
445:5x 89
781:11x 71
891:3x 3x 3x 3x 11
913:11x 83
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 11 = 121
Therefore, the value for common factors is 121.
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 = 282721949235/(1x121)
LCM = 282721949235/121
LCM = 2336545035
Thus, we can understand that the LCM of 445,781,891,913 is 2336545035.
