Given numbers are 281,645,635,717,263
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 281,645,635,717,263 is 1446849654555.
Find LCM of 281,645,635,717,263 with Prime Factorization
| 3 | 281, 645, 635, 717, 263 |
| 5 | 281, 215, 635, 239, 263 |
| 281, 43, 127, 239, 263 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 281 x 43 x 127 x 239 x 263 = 1446849654555
Therefore, the lowest common multiple of 281,645,635,717,263 is 1446849654555.
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.
281 x 645 x 635 x 717 x 263 = 21702744818325
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.
281 : 1, 281
645 : 1, 3, 5, 15, 43, 129, 215, 645
635 : 1, 5, 127, 635
717 : 1, 3, 239, 717
263 : 1, 263
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,645,635,717,263, is 1.
Now, the common factors can be found like this.
281:281
645:3x 5x 43
635:5x 127
717:3x 239
263:263
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5 = 15
Therefore, the value for common factors is 15.
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 = 21702744818325/(1x15)
LCM = 21702744818325/15
LCM = 1446849654555
Thus, we can understand that the LCM of 281,645,635,717,263 is 1446849654555.
