Given numbers are 621,885,878,516
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 621,885,878,516 is 13832688060.
Find LCM of 621,885,878,516 with Prime Factorization
| 2 | 621, 885, 878, 516 |
| 3 | 621, 885, 439, 258 |
| 207, 295, 439, 86 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 207 x 295 x 439 x 86 = 13832688060
Therefore, the lowest common multiple of 621,885,878,516 is 13832688060.
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.
621 x 885 x 878 x 516 = 248988385080
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.
621 : 1, 3, 9, 23, 27, 69, 207, 621
885 : 1, 3, 5, 15, 59, 177, 295, 885
878 : 1, 2, 439, 878
516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,885,878,516, is 1.
Now, the common factors can be found like this.
621:3x 3x 3x 23
885:3x 5x 59
878:2x 439
516:2x 2x 3x 43
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 3 = 18
Therefore, the value for common factors is 18.
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 = 248988385080/(1x18)
LCM = 248988385080/18
LCM = 13832688060
Thus, we can understand that the LCM of 621,885,878,516 is 13832688060.
