Given numbers are 142,789,856,923,916
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 142,789,856,923,916 is 142753889928.
Find LCM of 142,789,856,923,916 with Prime Factorization
| 2 | 142, 789, 856, 923, 916 |
| 2 | 71, 789, 428, 923, 458 |
| 71 | 71, 789, 214, 923, 229 |
| 1, 789, 214, 13, 229 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 71 x 1 x 789 x 214 x 13 x 229 = 142753889928
Therefore, the lowest common multiple of 142,789,856,923,916 is 142753889928.
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.
142 x 789 x 856 x 923 x 916 = 81084209479104
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.
142 : 1, 2, 71, 142
789 : 1, 3, 263, 789
856 : 1, 2, 4, 8, 107, 214, 428, 856
923 : 1, 13, 71, 923
916 : 1, 2, 4, 229, 458, 916
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 142,789,856,923,916, is 1.
Now, the common factors can be found like this.
142:2x 71
789:3x 263
856:2x 2x 2x 107
923:13x 71
916:2x 2x 229
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 71 = 568
Therefore, the value for common factors is 568.
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 = 81084209479104/(1x568)
LCM = 81084209479104/568
LCM = 142753889928
Thus, we can understand that the LCM of 142,789,856,923,916 is 142753889928.
