The LCM of 281,242,440,121,865 is 235286920.
Find LCM of 281,242,440,121,865 with Prime Factorization
| 2 | 281, 242, 440, 121, 865 |
| 5 | 281, 121, 220, 121, 865 |
| 11 | 281, 121, 44, 121, 173 |
| 11 | 281, 11, 4, 11, 173 |
| 281, 1, 4, 1, 173 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 11 x 281 x 1 x 4 x 1 x 173 = 235286920
Therefore, the lowest common multiple of 281,242,440,121,865 is 235286920.
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 242 x 440 x 121 x 865 = 3131668905200
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
242 : 1, 2, 11, 22, 121, 242
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
121 : 1, 11, 121
865 : 1, 5, 173, 865
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,242,440,121,865, is 1.
Now, the common factors can be found like this.
281:281
242:2x 11x 11
440:2x 2x 2x 5x 11
121:11x 11
865:5x 173
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 11x 11x 11 = 13310
Therefore, the value for common factors is 13310.
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 = 3131668905200/(1x13310)
LCM = 3131668905200/13310
LCM = 235286920
Thus, we can understand that the LCM of 281,242,440,121,865 is 235286920.
