Given numbers are 178,940,789,423,503
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 178,940,789,423,503 is 99605679660.
Find LCM of 178,940,789,423,503 with Prime Factorization
| 2 | 178, 940, 789, 423, 503 |
| 3 | 89, 470, 789, 423, 503 |
| 47 | 89, 470, 263, 141, 503 |
| 89, 10, 263, 3, 503 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 47 x 89 x 10 x 263 x 3 x 503 = 99605679660
Therefore, the lowest common multiple of 178,940,789,423,503 is 99605679660.
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.
178 x 940 x 789 x 423 x 503 = 28088801664120
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.
178 : 1, 2, 89, 178
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
789 : 1, 3, 263, 789
423 : 1, 3, 9, 47, 141, 423
503 : 1, 503
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 178,940,789,423,503, is 1.
Now, the common factors can be found like this.
178:2x 89
940:2x 2x 5x 47
789:3x 263
423:3x 3x 47
503:503
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 47 = 282
Therefore, the value for common factors is 282.
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 = 28088801664120/(1x282)
LCM = 28088801664120/282
LCM = 99605679660
Thus, we can understand that the LCM of 178,940,789,423,503 is 99605679660.
