Given numbers are 283,893,903,645,789
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 283,893,903,645,789 is 300089912955.
Find LCM of 283,893,903,645,789 with Prime Factorization
| 3 | 283, 893, 903, 645, 789 |
| 43 | 283, 893, 301, 215, 263 |
| 283, 893, 7, 5, 263 |
Multiply the prime numbers at the bottom and the left side.
3 x 43 x 283 x 893 x 7 x 5 x 263 = 300089912955
Therefore, the lowest common multiple of 283,893,903,645,789 is 300089912955.
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.
283 x 893 x 903 x 645 x 789 = 116134796313585
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.
283 : 1, 283
893 : 1, 19, 47, 893
903 : 1, 3, 7, 21, 43, 129, 301, 903
645 : 1, 3, 5, 15, 43, 129, 215, 645
789 : 1, 3, 263, 789
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 283,893,903,645,789, is 1.
Now, the common factors can be found like this.
283:283
893:19x 47
903:3x 7x 43
645:3x 5x 43
789:3x 263
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 43 = 387
Therefore, the value for common factors is 387.
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 = 116134796313585/(1x387)
LCM = 116134796313585/387
LCM = 300089912955
Thus, we can understand that the LCM of 283,893,903,645,789 is 300089912955.
