Given numbers are 515,245,721,187
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 515,245,721,187 is 4718945.
Find LCM of 515,245,721,187 with Prime Factorization
| 5 | 515, 245, 721, 187 |
| 7 | 103, 49, 721, 187 |
| 103 | 103, 7, 103, 187 |
| 1, 7, 1, 187 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 103 x 1 x 7 x 1 x 187 = 4718945
Therefore, the lowest common multiple of 515,245,721,187 is 4718945.
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.
515 x 245 x 721 x 187 = 17011796725
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.
515 : 1, 5, 103, 515
245 : 1, 5, 7, 35, 49, 245
721 : 1, 7, 103, 721
187 : 1, 11, 17, 187
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 515,245,721,187, is 1.
Now, the common factors can be found like this.
515:5x 103
245:5x 7x 7
721:7x 103
187:11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 7x 103 = 3605
Therefore, the value for common factors is 3605.
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 = 17011796725/(1x3605)
LCM = 17011796725/3605
LCM = 4718945
Thus, we can understand that the LCM of 515,245,721,187 is 4718945.
