Given numbers are 115,357,565,791
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 115,357,565,791 is 4639215.
Find LCM of 115,357,565,791 with Prime Factorization
| 5 | 115, 357, 565, 791 |
| 7 | 23, 357, 113, 791 |
| 113 | 23, 51, 113, 113 |
| 23, 51, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 113 x 23 x 51 x 1 x 1 = 4639215
Therefore, the lowest common multiple of 115,357,565,791 is 4639215.
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.
115 x 357 x 565 x 791 = 18348095325
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.
115 : 1, 5, 23, 115
357 : 1, 3, 7, 17, 21, 51, 119, 357
565 : 1, 5, 113, 565
791 : 1, 7, 113, 791
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 115,357,565,791, is 1.
Now, the common factors can be found like this.
115:5x 23
357:3x 7x 17
565:5x 113
791:7x 113
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 113 = 3955
Therefore, the value for common factors is 3955.
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 = 18348095325/(1x3955)
LCM = 18348095325/3955
LCM = 4639215
Thus, we can understand that the LCM of 115,357,565,791 is 4639215.
