Given numbers are 181,481,949,657
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 181,481,949,657 is 57199077.
Find LCM of 181,481,949,657 with Prime Factorization
| 13 | 181, 481, 949, 657 |
| 73 | 181, 37, 73, 657 |
| 181, 37, 1, 9 |
Multiply the prime numbers at the bottom and the left side.
13 x 73 x 181 x 37 x 1 x 9 = 57199077
Therefore, the lowest common multiple of 181,481,949,657 is 57199077.
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.
181 x 481 x 949 x 657 = 54281924073
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.
181 : 1, 181
481 : 1, 13, 37, 481
949 : 1, 13, 73, 949
657 : 1, 3, 9, 73, 219, 657
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 181,481,949,657, is 1.
Now, the common factors can be found like this.
181:181
481:13x 37
949:13x 73
657:3x 3x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 73 = 949
Therefore, the value for common factors is 949.
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 = 54281924073/(1x949)
LCM = 54281924073/949
LCM = 57199077
Thus, we can understand that the LCM of 181,481,949,657 is 57199077.
