Given numbers are 689,526,686,197
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 689,526,686,197 is 24488676394.
Find LCM of 689,526,686,197 with Prime Factorization
| 2 | 689, 526, 686, 197 |
| 689, 263, 343, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 689 x 263 x 343 x 197 = 24488676394
Therefore, the lowest common multiple of 689,526,686,197 is 24488676394.
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.
689 x 526 x 686 x 197 = 48977352788
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.
689 : 1, 13, 53, 689
526 : 1, 2, 263, 526
686 : 1, 2, 7, 14, 49, 98, 343, 686
197 : 1, 197
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,526,686,197, is 1.
Now, the common factors can be found like this.
689:13x 53
526:2x 263
686:2x 7x 7x 7
197:197
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 48977352788/(1x2)
LCM = 48977352788/2
LCM = 24488676394
Thus, we can understand that the LCM of 689,526,686,197 is 24488676394.
