Find LCM of 684,143,912,331 with Prime Factorization
| 2 | 684, 143, 912, 331 |
| 2 | 342, 143, 456, 331 |
| 3 | 171, 143, 228, 331 |
| 19 | 57, 143, 76, 331 |
| 3, 143, 4, 331 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 19 x 3 x 143 x 4 x 331 = 129503088
Therefore, the lowest common multiple of 684,143,912,331 is 129503088.
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.
684 x 143 x 912 x 331 = 29526704064
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.
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
143 : 1, 11, 13, 143
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
331 : 1, 331
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,143,912,331, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
143:11x 13
912:2x 2x 2x 2x 3x 19
331:331
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 19 = 228
Therefore, the value for common factors is 228.
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 = 29526704064/(1x228)
LCM = 29526704064/228
LCM = 129503088
Thus, we can understand that the LCM of 684,143,912,331 is 129503088.
