Find LCM of 806,403,618,384 with Prime Factorization
| 2 | 806, 403, 618, 384 |
| 3 | 403, 403, 309, 192 |
| 13 | 403, 403, 103, 64 |
| 31 | 31, 31, 103, 64 |
| 1, 1, 103, 64 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 31 x 1 x 1 x 103 x 64 = 15939456
Therefore, the lowest common multiple of 806,403,618,384 is 15939456.
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.
806 x 403 x 618 x 384 = 77083209216
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.
806 : 1, 2, 13, 26, 31, 62, 403, 806
403 : 1, 13, 31, 403
618 : 1, 2, 3, 6, 103, 206, 309, 618
384 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 806,403,618,384, is 1.
Now, the common factors can be found like this.
806:2x 13x 31
403:13x 31
618:2x 3x 103
384:2x 2x 2x 2x 2x 2x 2x 3
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 13x 31 = 4836
Therefore, the value for common factors is 4836.
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 = 77083209216/(1x4836)
LCM = 77083209216/4836
LCM = 15939456
Thus, we can understand that the LCM of 806,403,618,384 is 15939456.
