Given numbers are 123,781,979,779,876
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 123,781,979,779,876 is 47433219636.
Find LCM of 123,781,979,779,876 with Prime Factorization
| 3 | 123, 781, 979, 779, 876 |
| 11 | 41, 781, 979, 779, 292 |
| 41 | 41, 71, 89, 779, 292 |
| 1, 71, 89, 19, 292 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 41 x 1 x 71 x 89 x 19 x 292 = 47433219636
Therefore, the lowest common multiple of 123,781,979,779,876 is 47433219636.
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.
123 x 781 x 979 x 779 x 876 = 64177146167508
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.
123 : 1, 3, 41, 123
781 : 1, 11, 71, 781
979 : 1, 11, 89, 979
779 : 1, 19, 41, 779
876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 123,781,979,779,876, is 1.
Now, the common factors can be found like this.
123:3x 41
781:11x 71
979:11x 89
779:19x 41
876:2x 2x 3x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 41 = 1353
Therefore, the value for common factors is 1353.
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 = 64177146167508/(1x1353)
LCM = 64177146167508/1353
LCM = 47433219636
Thus, we can understand that the LCM of 123,781,979,779,876 is 47433219636.
