The LCM of 804,123,656,845 is 111418320.
Find LCM of 804,123,656,845 with Prime Factorization
| 2 | 804, 123, 656, 845 |
| 2 | 402, 123, 328, 845 |
| 3 | 201, 123, 164, 845 |
| 41 | 67, 41, 164, 845 |
| 67, 1, 4, 845 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 41 x 67 x 1 x 4 x 845 = 111418320
Therefore, the lowest common multiple of 804,123,656,845 is 111418320.
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.
804 x 123 x 656 x 845 = 54817813440
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.
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
123 : 1, 3, 41, 123
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
845 : 1, 5, 13, 65, 169, 845
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 804,123,656,845, is 1.
Now, the common factors can be found like this.
804:2x 2x 3x 67
123:3x 41
656:2x 2x 2x 2x 41
845:5x 13x 13
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 3x 41 = 492
Therefore, the value for common factors is 492.
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 = 54817813440/(1x492)
LCM = 54817813440/492
LCM = 111418320
Thus, we can understand that the LCM of 804,123,656,845 is 111418320.
