Given numbers are 861,167,412,656
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 861,167,412,656 is 236960976.
Find LCM of 861,167,412,656 with Prime Factorization
| 2 | 861, 167, 412, 656 |
| 2 | 861, 167, 206, 328 |
| 41 | 861, 167, 103, 164 |
| 21, 167, 103, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 41 x 21 x 167 x 103 x 4 = 236960976
Therefore, the lowest common multiple of 861,167,412,656 is 236960976.
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.
861 x 167 x 412 x 656 = 38861600064
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.
861 : 1, 3, 7, 21, 41, 123, 287, 861
167 : 1, 167
412 : 1, 2, 4, 103, 206, 412
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,167,412,656, is 1.
Now, the common factors can be found like this.
861:3x 7x 41
167:167
412:2x 2x 103
656:2x 2x 2x 2x 41
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 41 = 164
Therefore, the value for common factors is 164.
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 = 38861600064/(1x164)
LCM = 38861600064/164
LCM = 236960976
Thus, we can understand that the LCM of 861,167,412,656 is 236960976.
