Given numbers are 815,457,477,745
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 815,457,477,745 is 26471494215.
Find LCM of 815,457,477,745 with Prime Factorization
| 5 | 815, 457, 477, 745 |
| 163, 457, 477, 149 |
Multiply the prime numbers at the bottom and the left side.
5 x 163 x 457 x 477 x 149 = 26471494215
Therefore, the lowest common multiple of 815,457,477,745 is 26471494215.
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.
815 x 457 x 477 x 745 = 132357471075
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.
815 : 1, 5, 163, 815
457 : 1, 457
477 : 1, 3, 9, 53, 159, 477
745 : 1, 5, 149, 745
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,457,477,745, is 1.
Now, the common factors can be found like this.
815:5x 163
457:457
477:3x 3x 53
745:5x 149
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
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 = 132357471075/(1x5)
LCM = 132357471075/5
LCM = 26471494215
Thus, we can understand that the LCM of 815,457,477,745 is 26471494215.
