Given numbers are 256,961,979,623,408
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 256,961,979,623,408 is 85983330048.
Find LCM of 256,961,979,623,408 with Prime Factorization
| 2 | 256, 961, 979, 623, 408 |
| 2 | 128, 961, 979, 623, 204 |
| 2 | 64, 961, 979, 623, 102 |
| 89 | 32, 961, 979, 623, 51 |
| 32, 961, 11, 7, 51 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 89 x 32 x 961 x 11 x 7 x 51 = 85983330048
Therefore, the lowest common multiple of 256,961,979,623,408 is 85983330048.
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.
256 x 961 x 979 x 623 x 408 = 61220130994176
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.
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
961 : 1, 31, 961
979 : 1, 11, 89, 979
623 : 1, 7, 89, 623
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 256,961,979,623,408, is 1.
Now, the common factors can be found like this.
256:2x 2x 2x 2x 2x 2x 2x 2
961:31x 31
979:11x 89
623:7x 89
408:2x 2x 2x 3x 17
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 89 = 712
Therefore, the value for common factors is 712.
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 = 61220130994176/(1x712)
LCM = 61220130994176/712
LCM = 85983330048
Thus, we can understand that the LCM of 256,961,979,623,408 is 85983330048.
