Find LCM of 822,218,411,833,686 with Prime Factorization
| 2 | 822, 218, 411, 833, 686 |
| 3 | 411, 109, 411, 833, 343 |
| 7 | 137, 109, 137, 833, 343 |
| 7 | 137, 109, 137, 119, 49 |
| 137 | 137, 109, 137, 17, 7 |
| 1, 109, 1, 17, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 7 x 137 x 1 x 109 x 1 x 17 x 7 = 522445938
Therefore, the lowest common multiple of 822,218,411,833,686 is 522445938.
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 218 x 411 x 833 x 686 = 42086154981528
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
218 : 1, 2, 109, 218
411 : 1, 3, 137, 411
833 : 1, 7, 17, 49, 119, 833
686 : 1, 2, 7, 14, 49, 98, 343, 686
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 822,218,411,833,686, is 1.
Now, the common factors can be found like this.
822:2x 3x 137
218:2x 109
411:3x 137
833:7x 7x 17
686:2x 7x 7x 7
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 3x 7x 7x 137 = 80556
Therefore, the value for common factors is 80556.
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 = 42086154981528/(1x80556)
LCM = 42086154981528/80556
LCM = 522445938
Thus, we can understand that the LCM of 822,218,411,833,686 is 522445938.
