Given numbers are 872,241,646,964
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 872,241,646,964 is 67879096.
Find LCM of 872,241,646,964 with Prime Factorization
| 2 | 872, 241, 646, 964 |
| 2 | 436, 241, 323, 482 |
| 241 | 218, 241, 323, 241 |
| 218, 1, 323, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 241 x 218 x 1 x 323 x 1 = 67879096
Therefore, the lowest common multiple of 872,241,646,964 is 67879096.
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.
872 x 241 x 646 x 964 = 130870897088
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.
872 : 1, 2, 4, 8, 109, 218, 436, 872
241 : 1, 241
646 : 1, 2, 17, 19, 34, 38, 323, 646
964 : 1, 2, 4, 241, 482, 964
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 872,241,646,964, is 1.
Now, the common factors can be found like this.
872:2x 2x 2x 109
241:241
646:2x 17x 19
964:2x 2x 241
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 2x 241 = 1928
Therefore, the value for common factors is 1928.
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 = 130870897088/(1x1928)
LCM = 130870897088/1928
LCM = 67879096
Thus, we can understand that the LCM of 872,241,646,964 is 67879096.
