Given numbers are 686,581,996,986
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 686,581,996,986 is 168422604.
Find LCM of 686,581,996,986 with Prime Factorization
2 | 686, 581, 996, 986 |
7 | 343, 581, 498, 493 |
83 | 49, 83, 498, 493 |
49, 1, 6, 493 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 83 x 49 x 1 x 6 x 493 = 168422604
Therefore, the lowest common multiple of 686,581,996,986 is 168422604.
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.
686 x 581 x 996 x 986 = 391414131696
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.
686 : 1, 2, 7, 14, 49, 98, 343, 686
581 : 1, 7, 83, 581
996 : 1, 2, 3, 4, 6, 12, 83, 166, 249, 332, 498, 996
986 : 1, 2, 17, 29, 34, 58, 493, 986
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,581,996,986, is 1.
Now, the common factors can be found like this.
686:2x 7x 7x 7
581:7x 83
996:2x 2x 3x 83
986:2x 17x 29
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 7x 83 = 2324
Therefore, the value for common factors is 2324.
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 = 391414131696/(1x2324)
LCM = 391414131696/2324
LCM = 168422604
Thus, we can understand that the LCM of 686,581,996,986 is 168422604.
