Find LCM of 804,862,684,399 with Prime Factorization
| 2 | 804, 862, 684, 399 |
| 2 | 402, 431, 342, 399 |
| 3 | 201, 431, 171, 399 |
| 19 | 67, 431, 57, 133 |
| 67, 431, 3, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 19 x 67 x 431 x 3 x 7 = 138263076
Therefore, the lowest common multiple of 804,862,684,399 is 138263076.
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.
804 x 862 x 684 x 399 = 189143887968
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.
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
862 : 1, 2, 431, 862
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
399 : 1, 3, 7, 19, 21, 57, 133, 399
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 804,862,684,399, is 1.
Now, the common factors can be found like this.
804:2x 2x 3x 67
862:2x 431
684:2x 2x 3x 3x 19
399:3x 7x 19
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 3x 19 = 1368
Therefore, the value for common factors is 1368.
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 = 189143887968/(1x1368)
LCM = 189143887968/1368
LCM = 138263076
Thus, we can understand that the LCM of 804,862,684,399 is 138263076.
