Find LCM of 884,494,644,989 with Prime Factorization
| 2 | 884, 494, 644, 989 |
| 2 | 442, 247, 322, 989 |
| 13 | 221, 247, 161, 989 |
| 23 | 17, 19, 161, 989 |
| 17, 19, 7, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 23 x 17 x 19 x 7 x 43 = 116278708
Therefore, the lowest common multiple of 884,494,644,989 is 116278708.
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.
884 x 494 x 644 x 989 = 278138669536
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.
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
494 : 1, 2, 13, 19, 26, 38, 247, 494
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 884,494,644,989, is 1.
Now, the common factors can be found like this.
884:2x 2x 13x 17
494:2x 13x 19
644:2x 2x 7x 23
989:23x 43
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 13x 23 = 2392
Therefore, the value for common factors is 2392.
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 = 278138669536/(1x2392)
LCM = 278138669536/2392
LCM = 116278708
Thus, we can understand that the LCM of 884,494,644,989 is 116278708.
