Given numbers are 243,643,699,514
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 243,643,699,514 is 18712692738.
Find LCM of 243,643,699,514 with Prime Factorization
| 3 | 243, 643, 699, 514 |
| 81, 643, 233, 514 |
Multiply the prime numbers at the bottom and the left side.
3 x 81 x 643 x 233 x 514 = 18712692738
Therefore, the lowest common multiple of 243,643,699,514 is 18712692738.
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.
243 x 643 x 699 x 514 = 56138078214
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.
243 : 1, 3, 9, 27, 81, 243
643 : 1, 643
699 : 1, 3, 233, 699
514 : 1, 2, 257, 514
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 243,643,699,514, is 1.
Now, the common factors can be found like this.
243:3x 3x 3x 3x 3
643:643
699:3x 233
514:2x 257
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 56138078214/(1x3)
LCM = 56138078214/3
LCM = 18712692738
Thus, we can understand that the LCM of 243,643,699,514 is 18712692738.
