The LCM of 654,978,800,160 is 42640800.
Find LCM of 654,978,800,160 with Prime Factorization
| 2 | 654, 978, 800, 160 |
| 2 | 327, 489, 400, 80 |
| 2 | 327, 489, 200, 40 |
| 2 | 327, 489, 100, 20 |
| 2 | 327, 489, 50, 10 |
| 3 | 327, 489, 25, 5 |
| 5 | 109, 163, 25, 5 |
| 109, 163, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 3 x 5 x 109 x 163 x 1 x 5 = 42640800
Therefore, the lowest common multiple of 654,978,800,160 is 42640800.
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.
654 x 978 x 800 x 160 = 81870336000
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.
654 : 1, 2, 3, 6, 109, 218, 327, 654
978 : 1, 2, 3, 6, 163, 326, 489, 978
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 654,978,800,160, is 2.
Now, the common factors can be found like this.
654:2x 3x 109
978:2x 3x 163
800:2x 2x 2x 2x 2x 5x 5
160:2x 2x 2x 2x 2x 5
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 2x 2x 2x 3x 5 = 960
Therefore, the value for common factors is 960.
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 = 81870336000/(2x960)
LCM = 81870336000/1920
LCM = 42640800
Thus, we can understand that the LCM of 654,978,800,160 is 42640800.
