Given numbers are 669,986,731,789,844
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 669,986,731,789,844 is 3148035982332.
Find LCM of 669,986,731,789,844 with Prime Factorization
| 2 | 669, 986, 731, 789, 844 |
| 3 | 669, 493, 731, 789, 422 |
| 17 | 223, 493, 731, 263, 422 |
| 223, 29, 43, 263, 422 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 223 x 29 x 43 x 263 x 422 = 3148035982332
Therefore, the lowest common multiple of 669,986,731,789,844 is 3148035982332.
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.
669 x 986 x 731 x 789 x 844 = 321099670197864
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.
669 : 1, 3, 223, 669
986 : 1, 2, 17, 29, 34, 58, 493, 986
731 : 1, 17, 43, 731
789 : 1, 3, 263, 789
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 669,986,731,789,844, is 1.
Now, the common factors can be found like this.
669:3x 223
986:2x 17x 29
731:17x 43
789:3x 263
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 17 = 102
Therefore, the value for common factors is 102.
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 = 321099670197864/(1x102)
LCM = 321099670197864/102
LCM = 3148035982332
Thus, we can understand that the LCM of 669,986,731,789,844 is 3148035982332.
