Given numbers are 404,255,998,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 404,255,998,221 is 668290740.
Find LCM of 404,255,998,221 with Prime Factorization
| 2 | 404, 255, 998, 221 |
| 17 | 202, 255, 499, 221 |
| 202, 15, 499, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 202 x 15 x 499 x 13 = 668290740
Therefore, the lowest common multiple of 404,255,998,221 is 668290740.
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.
404 x 255 x 998 x 221 = 22721885160
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.
404 : 1, 2, 4, 101, 202, 404
255 : 1, 3, 5, 15, 17, 51, 85, 255
998 : 1, 2, 499, 998
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 404,255,998,221, is 1.
Now, the common factors can be found like this.
404:2x 2x 101
255:3x 5x 17
998:2x 499
221:13x 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 17 = 34
Therefore, the value for common factors is 34.
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 = 22721885160/(1x34)
LCM = 22721885160/34
LCM = 668290740
Thus, we can understand that the LCM of 404,255,998,221 is 668290740.
