Find LCM of 972,897,644,243 with Prime Factorization
| 2 | 972, 897, 644, 243 |
| 2 | 486, 897, 322, 243 |
| 3 | 243, 897, 161, 243 |
| 3 | 81, 299, 161, 81 |
| 3 | 27, 299, 161, 27 |
| 3 | 9, 299, 161, 9 |
| 3 | 3, 299, 161, 3 |
| 23 | 1, 299, 161, 1 |
| 1, 13, 7, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 3 x 3 x 23 x 1 x 13 x 7 x 1 = 2034396
Therefore, the lowest common multiple of 972,897,644,243 is 2034396.
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.
972 x 897 x 644 x 243 = 136442870928
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.
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
897 : 1, 3, 13, 23, 39, 69, 299, 897
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
243 : 1, 3, 9, 27, 81, 243
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 972,897,644,243, is 1.
Now, the common factors can be found like this.
972:2x 2x 3x 3x 3x 3x 3
897:3x 13x 23
644:2x 2x 7x 23
243:3x 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 3x 3x 3x 3x 3x 23 = 67068
Therefore, the value for common factors is 67068.
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 = 136442870928/(1x67068)
LCM = 136442870928/67068
LCM = 2034396
Thus, we can understand that the LCM of 972,897,644,243 is 2034396.
