Given numbers are 855,964,663,928
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 855,964,663,928 is 42259407840.
Find LCM of 855,964,663,928 with Prime Factorization
| 2 | 855, 964, 663, 928 |
| 2 | 855, 482, 663, 464 |
| 3 | 855, 241, 663, 232 |
| 285, 241, 221, 232 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 285 x 241 x 221 x 232 = 42259407840
Therefore, the lowest common multiple of 855,964,663,928 is 42259407840.
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.
855 x 964 x 663 x 928 = 507112894080
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.
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
964 : 1, 2, 4, 241, 482, 964
663 : 1, 3, 13, 17, 39, 51, 221, 663
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,964,663,928, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
964:2x 2x 241
663:3x 13x 17
928:2x 2x 2x 2x 2x 29
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 3 = 12
Therefore, the value for common factors is 12.
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 = 507112894080/(1x12)
LCM = 507112894080/12
LCM = 42259407840
Thus, we can understand that the LCM of 855,964,663,928 is 42259407840.
