Find LCM of 819,554,924,644 with Prime Factorization
| 2 | 819, 554, 924, 644 |
| 2 | 819, 277, 462, 322 |
| 3 | 819, 277, 231, 161 |
| 7 | 273, 277, 77, 161 |
| 39, 277, 11, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 39 x 277 x 11 x 23 = 229585356
Therefore, the lowest common multiple of 819,554,924,644 is 229585356.
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.
819 x 554 x 924 x 644 = 269992378656
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.
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
554 : 1, 2, 277, 554
924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 819,554,924,644, is 1.
Now, the common factors can be found like this.
819:3x 3x 7x 13
554:2x 277
924:2x 2x 3x 7x 11
644:2x 2x 7x 23
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 3x 7x 7 = 1176
Therefore, the value for common factors is 1176.
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 = 269992378656/(1x1176)
LCM = 269992378656/1176
LCM = 229585356
Thus, we can understand that the LCM of 819,554,924,644 is 229585356.
