Given numbers are 144,865,685,162
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 144,865,685,162 is 153582480.
Find LCM of 144,865,685,162 with Prime Factorization
| 2 | 144, 865, 685, 162 |
| 3 | 72, 865, 685, 81 |
| 3 | 24, 865, 685, 27 |
| 5 | 8, 865, 685, 9 |
| 8, 173, 137, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 8 x 173 x 137 x 9 = 153582480
Therefore, the lowest common multiple of 144,865,685,162 is 153582480.
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.
144 x 865 x 685 x 162 = 13822423200
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.
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
865 : 1, 5, 173, 865
685 : 1, 5, 137, 685
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 144,865,685,162, is 1.
Now, the common factors can be found like this.
144:2x 2x 2x 2x 3x 3
865:5x 173
685:5x 137
162:2x 3x 3x 3x 3
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 3x 5 = 90
Therefore, the value for common factors is 90.
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 = 13822423200/(1x90)
LCM = 13822423200/90
LCM = 153582480
Thus, we can understand that the LCM of 144,865,685,162 is 153582480.
