Given numbers are 218,992,310,514
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 218,992,310,514 is 138944480.
Find LCM of 218,992,310,514 with Prime Factorization
| 2 | 218, 992, 310, 514 |
| 31 | 109, 496, 155, 257 |
| 109, 16, 5, 257 |
Multiply the prime numbers at the bottom and the left side.
2 x 31 x 109 x 16 x 5 x 257 = 138944480
Therefore, the lowest common multiple of 218,992,310,514 is 138944480.
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.
218 x 992 x 310 x 514 = 34458231040
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.
218 : 1, 2, 109, 218
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
310 : 1, 2, 5, 10, 31, 62, 155, 310
514 : 1, 2, 257, 514
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 218,992,310,514, is 2.
Now, the common factors can be found like this.
218:2x 109
992:2x 2x 2x 2x 2x 31
310:2x 5x 31
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.
2x 2x 31 = 124
Therefore, the value for common factors is 124.
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 = 34458231040/(2x124)
LCM = 34458231040/248
LCM = 138944480
Thus, we can understand that the LCM of 218,992,310,514 is 138944480.
