Given numbers are 303,645,862,865,388
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 303,645,862,865,388 is 1884673774380.
Find LCM of 303,645,862,865,388 with Prime Factorization
| 2 | 303, 645, 862, 865, 388 |
| 3 | 303, 645, 431, 865, 194 |
| 5 | 101, 215, 431, 865, 194 |
| 101, 43, 431, 173, 194 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 101 x 43 x 431 x 173 x 194 = 1884673774380
Therefore, the lowest common multiple of 303,645,862,865,388 is 1884673774380.
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.
303 x 645 x 862 x 865 x 388 = 56540213231400
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.
303 : 1, 3, 101, 303
645 : 1, 3, 5, 15, 43, 129, 215, 645
862 : 1, 2, 431, 862
865 : 1, 5, 173, 865
388 : 1, 2, 4, 97, 194, 388
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 303,645,862,865,388, is 1.
Now, the common factors can be found like this.
303:3x 101
645:3x 5x 43
862:2x 431
865:5x 173
388:2x 2x 97
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 5 = 30
Therefore, the value for common factors is 30.
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 = 56540213231400/(1x30)
LCM = 56540213231400/30
LCM = 1884673774380
Thus, we can understand that the LCM of 303,645,862,865,388 is 1884673774380.
