Given numbers are 741,487,471,813
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 741,487,471,813 is 15353808249.
Find LCM of 741,487,471,813 with Prime Factorization
| 3 | 741, 487, 471, 813 |
| 247, 487, 157, 271 |
Multiply the prime numbers at the bottom and the left side.
3 x 247 x 487 x 157 x 271 = 15353808249
Therefore, the lowest common multiple of 741,487,471,813 is 15353808249.
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.
741 x 487 x 471 x 813 = 138184274241
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.
741 : 1, 3, 13, 19, 39, 57, 247, 741
487 : 1, 487
471 : 1, 3, 157, 471
813 : 1, 3, 271, 813
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 741,487,471,813, is 1.
Now, the common factors can be found like this.
741:3x 13x 19
487:487
471:3x 157
813:3x 271
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 138184274241/(1x9)
LCM = 138184274241/9
LCM = 15353808249
Thus, we can understand that the LCM of 741,487,471,813 is 15353808249.
