Find LCM of 223,945,855,117,521 with Prime Factorization
| 3 | 223, 945, 855, 117, 521 |
| 3 | 223, 315, 285, 39, 521 |
| 5 | 223, 105, 95, 13, 521 |
| 223, 21, 19, 13, 521 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 223 x 21 x 19 x 13 x 521 = 27118854945
Therefore, the lowest common multiple of 223,945,855,117,521 is 27118854945.
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.
223 x 945 x 855 x 117 x 521 = 10983136252725
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.
223 : 1, 223
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
117 : 1, 3, 9, 13, 39, 117
521 : 1, 521
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 223,945,855,117,521, is 1.
Now, the common factors can be found like this.
223:223
945:3x 3x 3x 5x 7
855:3x 3x 5x 19
117:3x 3x 13
521:521
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 5 = 405
Therefore, the value for common factors is 405.
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 = 10983136252725/(1x405)
LCM = 10983136252725/405
LCM = 27118854945
Thus, we can understand that the LCM of 223,945,855,117,521 is 27118854945.
