Find LCM of 822,744,608,682,642 with Prime Factorization
| 2 | 822, 744, 608, 682, 642 |
| 2 | 411, 372, 304, 341, 321 |
| 2 | 411, 186, 152, 341, 321 |
| 3 | 411, 93, 76, 341, 321 |
| 31 | 137, 31, 76, 341, 107 |
| 137, 1, 76, 11, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 31 x 137 x 1 x 76 x 11 x 107 = 9117663456
Therefore, the lowest common multiple of 822,744,608,682,642 is 9117663456.
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.
822 x 744 x 608 x 682 x 642 = 162804998670336
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.
822 : 1, 2, 3, 6, 137, 274, 411, 822
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
608 : 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304, 608
682 : 1, 2, 11, 22, 31, 62, 341, 682
642 : 1, 2, 3, 6, 107, 214, 321, 642
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 822,744,608,682,642, is 2.
Now, the common factors can be found like this.
822:2x 3x 137
744:2x 2x 2x 3x 31
608:2x 2x 2x 2x 2x 19
682:2x 11x 31
642:2x 3x 107
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 3x 3x 31 = 8928
Therefore, the value for common factors is 8928.
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 = 162804998670336/(2x8928)
LCM = 162804998670336/17856
LCM = 9117663456
Thus, we can understand that the LCM of 822,744,608,682,642 is 9117663456.
