The LCM of 387,154,966,144 is 10966032.
Find LCM of 387,154,966,144 with Prime Factorization
| 2 | 387, 154, 966, 144 |
| 3 | 387, 77, 483, 72 |
| 3 | 129, 77, 161, 24 |
| 7 | 43, 77, 161, 8 |
| 43, 11, 23, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 43 x 11 x 23 x 8 = 10966032
Therefore, the lowest common multiple of 387,154,966,144 is 10966032.
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.
387 x 154 x 966 x 144 = 8290320192
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.
387 : 1, 3, 9, 43, 129, 387
154 : 1, 2, 7, 11, 14, 22, 77, 154
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 387,154,966,144, is 1.
Now, the common factors can be found like this.
387:3x 3x 43
154:2x 7x 11
966:2x 3x 7x 23
144:2x 2x 2x 2x 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 7 = 756
Therefore, the value for common factors is 756.
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 = 8290320192/(1x756)
LCM = 8290320192/756
LCM = 10966032
Thus, we can understand that the LCM of 387,154,966,144 is 10966032.
