Given numbers are 893,545,285,129
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 893,545,285,129 is 62782365.
Find LCM of 893,545,285,129 with Prime Factorization
| 3 | 893, 545, 285, 129 |
| 5 | 893, 545, 95, 43 |
| 19 | 893, 109, 19, 43 |
| 47, 109, 1, 43 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 19 x 47 x 109 x 1 x 43 = 62782365
Therefore, the lowest common multiple of 893,545,285,129 is 62782365.
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.
893 x 545 x 285 x 129 = 17892974025
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.
893 : 1, 19, 47, 893
545 : 1, 5, 109, 545
285 : 1, 3, 5, 15, 19, 57, 95, 285
129 : 1, 3, 43, 129
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 893,545,285,129, is 1.
Now, the common factors can be found like this.
893:19x 47
545:5x 109
285:3x 5x 19
129:3x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 19 = 285
Therefore, the value for common factors is 285.
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 = 17892974025/(1x285)
LCM = 17892974025/285
LCM = 62782365
Thus, we can understand that the LCM of 893,545,285,129 is 62782365.
