Given numbers are 672,979,687,317,751
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 672,979,687,317,751 is 35866305751584.
Find LCM of 672,979,687,317,751 with Prime Factorization
| 3 | 672, 979, 687, 317, 751 |
| 224, 979, 229, 317, 751 |
Multiply the prime numbers at the bottom and the left side.
3 x 224 x 979 x 229 x 317 x 751 = 35866305751584
Therefore, the lowest common multiple of 672,979,687,317,751 is 35866305751584.
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.
672 x 979 x 687 x 317 x 751 = 107598917254752
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.
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
979 : 1, 11, 89, 979
687 : 1, 3, 229, 687
317 : 1, 317
751 : 1, 751
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,979,687,317,751, is 1.
Now, the common factors can be found like this.
672:2x 2x 2x 2x 2x 3x 7
979:11x 89
687:3x 229
317:317
751:751
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 107598917254752/(1x3)
LCM = 107598917254752/3
LCM = 35866305751584
Thus, we can understand that the LCM of 672,979,687,317,751 is 35866305751584.
