Given numbers are 399,163,779,415
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 399,163,779,415 is 1106604555.
Find LCM of 399,163,779,415 with Prime Factorization
| 19 | 399, 163, 779, 415 |
| 21, 163, 41, 415 |
Multiply the prime numbers at the bottom and the left side.
19 x 21 x 163 x 41 x 415 = 1106604555
Therefore, the lowest common multiple of 399,163,779,415 is 1106604555.
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.
399 x 163 x 779 x 415 = 21025486545
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.
399 : 1, 3, 7, 19, 21, 57, 133, 399
163 : 1, 163
779 : 1, 19, 41, 779
415 : 1, 5, 83, 415
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,163,779,415, is 1.
Now, the common factors can be found like this.
399:3x 7x 19
163:163
779:19x 41
415:5x 83
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19 = 19
Therefore, the value for common factors is 19.
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 = 21025486545/(1x19)
LCM = 21025486545/19
LCM = 1106604555
Thus, we can understand that the LCM of 399,163,779,415 is 1106604555.
