Given numbers are 518,388,353,731,353
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 518,388,353,731,353 is 25931257156.
Find LCM of 518,388,353,731,353 with Prime Factorization
| 2 | 518, 388, 353, 731, 353 |
| 353 | 259, 194, 353, 731, 353 |
| 259, 194, 1, 731, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 353 x 259 x 194 x 1 x 731 x 1 = 25931257156
Therefore, the lowest common multiple of 518,388,353,731,353 is 25931257156.
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.
518 x 388 x 353 x 731 x 353 = 18307467552136
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.
518 : 1, 2, 7, 14, 37, 74, 259, 518
388 : 1, 2, 4, 97, 194, 388
353 : 1, 353
731 : 1, 17, 43, 731
353 : 1, 353
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 518,388,353,731,353, is 1.
Now, the common factors can be found like this.
518:2x 7x 37
388:2x 2x 97
353:353
731:17x 43
353:353
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 353 = 706
Therefore, the value for common factors is 706.
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 = 18307467552136/(1x706)
LCM = 18307467552136/706
LCM = 25931257156
Thus, we can understand that the LCM of 518,388,353,731,353 is 25931257156.
