Given numbers are 281,440,110,428
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 281,440,110,428 is 13229480.
Find LCM of 281,440,110,428 with Prime Factorization
| 2 | 281, 440, 110, 428 |
| 2 | 281, 220, 55, 214 |
| 5 | 281, 110, 55, 107 |
| 11 | 281, 22, 11, 107 |
| 281, 2, 1, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 281 x 2 x 1 x 107 = 13229480
Therefore, the lowest common multiple of 281,440,110,428 is 13229480.
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 440 x 110 x 428 = 5820971200
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
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
110 : 1, 2, 5, 10, 11, 22, 55, 110
428 : 1, 2, 4, 107, 214, 428
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,440,110,428, is 1.
Now, the common factors can be found like this.
281:281
440:2x 2x 2x 5x 11
110:2x 5x 11
428:2x 2x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 5x 11 = 440
Therefore, the value for common factors is 440.
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 = 5820971200/(1x440)
LCM = 5820971200/440
LCM = 13229480
Thus, we can understand that the LCM of 281,440,110,428 is 13229480.
