Given numbers are 662,687,754,687
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 662,687,754,687 is 171457338.
Find LCM of 662,687,754,687 with Prime Factorization
| 2 | 662, 687, 754, 687 |
| 3 | 331, 687, 377, 687 |
| 229 | 331, 229, 377, 229 |
| 331, 1, 377, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 229 x 331 x 1 x 377 x 1 = 171457338
Therefore, the lowest common multiple of 662,687,754,687 is 171457338.
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.
662 x 687 x 754 x 687 = 235582382412
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.
662 : 1, 2, 331, 662
687 : 1, 3, 229, 687
754 : 1, 2, 13, 26, 29, 58, 377, 754
687 : 1, 3, 229, 687
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 662,687,754,687, is 1.
Now, the common factors can be found like this.
662:2x 331
687:3x 229
754:2x 13x 29
687:3x 229
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 229 = 1374
Therefore, the value for common factors is 1374.
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 = 235582382412/(1x1374)
LCM = 235582382412/1374
LCM = 171457338
Thus, we can understand that the LCM of 662,687,754,687 is 171457338.
