Find LCM of 819,576,641,536 with Prime Factorization
| 2 | 819, 576, 641, 536 |
| 2 | 819, 288, 641, 268 |
| 2 | 819, 144, 641, 134 |
| 3 | 819, 72, 641, 67 |
| 3 | 273, 24, 641, 67 |
| 91, 8, 641, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 91 x 8 x 641 x 67 = 2251109952
Therefore, the lowest common multiple of 819,576,641,536 is 2251109952.
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 576 x 641 x 536 = 162079916544
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
576 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 64, 72, 96, 144, 192, 288, 576
641 : 1, 641
536 : 1, 2, 4, 8, 67, 134, 268, 536
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 819,576,641,536, is 1.
Now, the common factors can be found like this.
819:3x 3x 7x 13
576:2x 2x 2x 2x 2x 2x 3x 3
641:641
536:2x 2x 2x 67
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 3 = 72
Therefore, the value for common factors is 72.
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 = 162079916544/(1x72)
LCM = 162079916544/72
LCM = 2251109952
Thus, we can understand that the LCM of 819,576,641,536 is 2251109952.
