Find LCM of 912,138,224,843 with Prime Factorization
| 2 | 912, 138, 224, 843 |
| 2 | 456, 69, 112, 843 |
| 2 | 228, 69, 56, 843 |
| 2 | 114, 69, 28, 843 |
| 3 | 57, 69, 14, 843 |
| 19, 23, 14, 281 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 19 x 23 x 14 x 281 = 82519584
Therefore, the lowest common multiple of 912,138,224,843 is 82519584.
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.
912 x 138 x 224 x 843 = 23765640192
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.
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
138 : 1, 2, 3, 6, 23, 46, 69, 138
224 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 112, 224
843 : 1, 3, 281, 843
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 912,138,224,843, is 1.
Now, the common factors can be found like this.
912:2x 2x 2x 2x 3x 19
138:2x 3x 23
224:2x 2x 2x 2x 2x 7
843:3x 281
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 2x 2x 2x 3x 3 = 288
Therefore, the value for common factors is 288.
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 = 23765640192/(1x288)
LCM = 23765640192/288
LCM = 82519584
Thus, we can understand that the LCM of 912,138,224,843 is 82519584.
