Find LCM of 403,304,889,992,442 with Prime Factorization
| 2 | 403, 304, 889, 992, 442 |
| 2 | 403, 152, 889, 496, 221 |
| 2 | 403, 76, 889, 248, 221 |
| 2 | 403, 38, 889, 124, 221 |
| 13 | 403, 19, 889, 62, 221 |
| 31 | 31, 19, 889, 62, 17 |
| 1, 19, 889, 2, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 13 x 31 x 1 x 19 x 889 x 2 x 17 = 3703047712
Therefore, the lowest common multiple of 403,304,889,992,442 is 3703047712.
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.
403 x 304 x 889 x 992 x 442 = 47754503293952
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.
403 : 1, 13, 31, 403
304 : 1, 2, 4, 8, 16, 19, 38, 76, 152, 304
889 : 1, 7, 127, 889
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
442 : 1, 2, 13, 17, 26, 34, 221, 442
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,304,889,992,442, is 1.
Now, the common factors can be found like this.
403:13x 31
304:2x 2x 2x 2x 19
889:7x 127
992:2x 2x 2x 2x 2x 31
442:2x 13x 17
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 13x 31 = 12896
Therefore, the value for common factors is 12896.
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 = 47754503293952/(1x12896)
LCM = 47754503293952/12896
LCM = 3703047712
Thus, we can understand that the LCM of 403,304,889,992,442 is 3703047712.
