Given numbers are 799,913,561,257
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 799,913,561,257 is 562434477.
Find LCM of 799,913,561,257 with Prime Factorization
| 11 | 799, 913, 561, 257 |
| 17 | 799, 83, 51, 257 |
| 47, 83, 3, 257 |
Multiply the prime numbers at the bottom and the left side.
11 x 17 x 47 x 83 x 3 x 257 = 562434477
Therefore, the lowest common multiple of 799,913,561,257 is 562434477.
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.
799 x 913 x 561 x 257 = 105175247199
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.
799 : 1, 17, 47, 799
913 : 1, 11, 83, 913
561 : 1, 3, 11, 17, 33, 51, 187, 561
257 : 1, 257
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 799,913,561,257, is 1.
Now, the common factors can be found like this.
799:17x 47
913:11x 83
561:3x 11x 17
257:257
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 17 = 187
Therefore, the value for common factors is 187.
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 = 105175247199/(1x187)
LCM = 105175247199/187
LCM = 562434477
Thus, we can understand that the LCM of 799,913,561,257 is 562434477.
