Given numbers are 122,779,878,305
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 122,779,878,305 is 208608410.
Find LCM of 122,779,878,305 with Prime Factorization
| 2 | 122, 779, 878, 305 |
| 61 | 61, 779, 439, 305 |
| 1, 779, 439, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 61 x 1 x 779 x 439 x 5 = 208608410
Therefore, the lowest common multiple of 122,779,878,305 is 208608410.
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.
122 x 779 x 878 x 305 = 25450226020
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.
122 : 1, 2, 61, 122
779 : 1, 19, 41, 779
878 : 1, 2, 439, 878
305 : 1, 5, 61, 305
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 122,779,878,305, is 1.
Now, the common factors can be found like this.
122:2x 61
779:19x 41
878:2x 439
305:5x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 61 = 122
Therefore, the value for common factors is 122.
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 = 25450226020/(1x122)
LCM = 25450226020/122
LCM = 208608410
Thus, we can understand that the LCM of 122,779,878,305 is 208608410.
