Find LCM of 343,643,784,643,308 with Prime Factorization
| 2 | 343, 643, 784, 643, 308 |
| 2 | 343, 643, 392, 643, 154 |
| 7 | 343, 643, 196, 643, 77 |
| 7 | 49, 643, 28, 643, 11 |
| 643 | 7, 643, 4, 643, 11 |
| 7, 1, 4, 1, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 7 x 643 x 7 x 1 x 4 x 1 x 11 = 38816624
Therefore, the lowest common multiple of 343,643,784,643,308 is 38816624.
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.
343 x 643 x 784 x 643 x 308 = 34243870426304
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.
343 : 1, 7, 49, 343
643 : 1, 643
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
643 : 1, 643
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 343,643,784,643,308, is 1.
Now, the common factors can be found like this.
343:7x 7x 7
643:643
784:2x 2x 2x 2x 7x 7
643:643
308:2x 2x 7x 11
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 7x 7x 7x 643 = 882196
Therefore, the value for common factors is 882196.
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 = 34243870426304/(1x882196)
LCM = 34243870426304/882196
LCM = 38816624
Thus, we can understand that the LCM of 343,643,784,643,308 is 38816624.
