Find LCM of 389,481,949,243,972 with Prime Factorization
| 3 | 389, 481, 949, 243, 972 |
| 3 | 389, 481, 949, 81, 324 |
| 3 | 389, 481, 949, 27, 108 |
| 3 | 389, 481, 949, 9, 36 |
| 3 | 389, 481, 949, 3, 12 |
| 13 | 389, 481, 949, 1, 4 |
| 389, 37, 73, 1, 4 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 3 x 3 x 13 x 389 x 37 x 73 x 1 x 4 = 13276506204
Therefore, the lowest common multiple of 389,481,949,243,972 is 13276506204.
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.
389 x 481 x 949 x 243 x 972 = 41940483098436
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.
389 : 1, 389
481 : 1, 13, 37, 481
949 : 1, 13, 73, 949
243 : 1, 3, 9, 27, 81, 243
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 389,481,949,243,972, is 1.
Now, the common factors can be found like this.
389:389
481:13x 37
949:13x 73
243:3x 3x 3x 3x 3
972:2x 2x 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.
3x 3x 3x 3x 3x 13 = 3159
Therefore, the value for common factors is 3159.
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 = 41940483098436/(1x3159)
LCM = 41940483098436/3159
LCM = 13276506204
Thus, we can understand that the LCM of 389,481,949,243,972 is 13276506204.
