Given numbers are 486,687,641,438,266
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 486,687,641,438,266 is 692634758886.
Find LCM of 486,687,641,438,266 with Prime Factorization
| 2 | 486, 687, 641, 438, 266 |
| 3 | 243, 687, 641, 219, 133 |
| 81, 229, 641, 73, 133 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 81 x 229 x 641 x 73 x 133 = 692634758886
Therefore, the lowest common multiple of 486,687,641,438,266 is 692634758886.
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.
486 x 687 x 641 x 438 x 266 = 24934851319896
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.
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
687 : 1, 3, 229, 687
641 : 1, 641
438 : 1, 2, 3, 6, 73, 146, 219, 438
266 : 1, 2, 7, 14, 19, 38, 133, 266
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 486,687,641,438,266, is 1.
Now, the common factors can be found like this.
486:2x 3x 3x 3x 3x 3
687:3x 229
641:641
438:2x 3x 73
266:2x 7x 19
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 3 = 36
Therefore, the value for common factors is 36.
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 = 24934851319896/(1x36)
LCM = 24934851319896/36
LCM = 692634758886
Thus, we can understand that the LCM of 486,687,641,438,266 is 692634758886.
