Given numbers are 253,791,731,161
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 253,791,731,161 is 146289913.
Find LCM of 253,791,731,161 with Prime Factorization
| 7 | 253, 791, 731, 161 |
| 23 | 253, 113, 731, 23 |
| 11, 113, 731, 1 |
Multiply the prime numbers at the bottom and the left side.
7 x 23 x 11 x 113 x 731 x 1 = 146289913
Therefore, the lowest common multiple of 253,791,731,161 is 146289913.
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.
253 x 791 x 731 x 161 = 23552675993
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.
253 : 1, 11, 23, 253
791 : 1, 7, 113, 791
731 : 1, 17, 43, 731
161 : 1, 7, 23, 161
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 253,791,731,161, is 1.
Now, the common factors can be found like this.
253:11x 23
791:7x 113
731:17x 43
161:7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 23 = 161
Therefore, the value for common factors is 161.
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 = 23552675993/(1x161)
LCM = 23552675993/161
LCM = 146289913
Thus, we can understand that the LCM of 253,791,731,161 is 146289913.
