Find LCM of 221,845,195,404,648 with Prime Factorization
| 2 | 221, 845, 195, 404, 648 |
| 2 | 221, 845, 195, 202, 324 |
| 3 | 221, 845, 195, 101, 162 |
| 5 | 221, 845, 65, 101, 54 |
| 13 | 221, 169, 13, 101, 54 |
| 17, 1, 13, 101, 54 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 13 x 17 x 1 x 13 x 101 x 54 = 940160520
Therefore, the lowest common multiple of 221,845,195,404,648 is 940160520.
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.
221 x 845 x 195 x 404 x 648 = 9533227672800
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.
221 : 1, 13, 17, 221
845 : 1, 5, 13, 65, 169, 845
195 : 1, 3, 5, 13, 15, 39, 65, 195
404 : 1, 2, 4, 101, 202, 404
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,845,195,404,648, is 1.
Now, the common factors can be found like this.
221:13x 17
845:5x 13x 13
195:3x 5x 13
404:2x 2x 101
648:2x 2x 2x 3x 3x 3x 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 5x 13x 13 = 10140
Therefore, the value for common factors is 10140.
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 = 9533227672800/(1x10140)
LCM = 9533227672800/10140
LCM = 940160520
Thus, we can understand that the LCM of 221,845,195,404,648 is 940160520.
