Find LCM of 897,285,165,799,221 with Prime Factorization
| 3 | 897, 285, 165, 799, 221 |
| 5 | 299, 95, 55, 799, 221 |
| 13 | 299, 19, 11, 799, 221 |
| 17 | 23, 19, 11, 799, 17 |
| 23, 19, 11, 47, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 13 x 17 x 23 x 19 x 11 x 47 x 1 = 748954635
Therefore, the lowest common multiple of 897,285,165,799,221 is 748954635.
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.
897 x 285 x 165 x 799 x 221 = 7448353845075
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.
897 : 1, 3, 13, 23, 39, 69, 299, 897
285 : 1, 3, 5, 15, 19, 57, 95, 285
165 : 1, 3, 5, 11, 15, 33, 55, 165
799 : 1, 17, 47, 799
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 897,285,165,799,221, is 1.
Now, the common factors can be found like this.
897:3x 13x 23
285:3x 5x 19
165:3x 5x 11
799:17x 47
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.
3x 3x 5x 13x 17 = 9945
Therefore, the value for common factors is 9945.
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 = 7448353845075/(1x9945)
LCM = 7448353845075/9945
LCM = 748954635
Thus, we can understand that the LCM of 897,285,165,799,221 is 748954635.
