Given numbers are 786,986,884,447
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 786,986,884,447 is 1501167252.
Find LCM of 786,986,884,447 with Prime Factorization
| 2 | 786, 986, 884, 447 |
| 3 | 393, 493, 442, 447 |
| 17 | 131, 493, 442, 149 |
| 131, 29, 26, 149 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 131 x 29 x 26 x 149 = 1501167252
Therefore, the lowest common multiple of 786,986,884,447 is 1501167252.
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.
786 x 986 x 884 x 447 = 306238119408
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.
786 : 1, 2, 3, 6, 131, 262, 393, 786
986 : 1, 2, 17, 29, 34, 58, 493, 986
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
447 : 1, 3, 149, 447
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 786,986,884,447, is 1.
Now, the common factors can be found like this.
786:2x 3x 131
986:2x 17x 29
884:2x 2x 13x 17
447:3x 149
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 3x 17 = 204
Therefore, the value for common factors is 204.
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 = 306238119408/(1x204)
LCM = 306238119408/204
LCM = 1501167252
Thus, we can understand that the LCM of 786,986,884,447 is 1501167252.
