Given numbers are 401,899,665,395
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 401,899,665,395 is 18938814965.
Find LCM of 401,899,665,395 with Prime Factorization
| 5 | 401, 899, 665, 395 |
| 401, 899, 133, 79 |
Multiply the prime numbers at the bottom and the left side.
5 x 401 x 899 x 133 x 79 = 18938814965
Therefore, the lowest common multiple of 401,899,665,395 is 18938814965.
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.
401 x 899 x 665 x 395 = 94694074825
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.
401 : 1, 401
899 : 1, 29, 31, 899
665 : 1, 5, 7, 19, 35, 95, 133, 665
395 : 1, 5, 79, 395
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 401,899,665,395, is 1.
Now, the common factors can be found like this.
401:401
899:29x 31
665:5x 7x 19
395:5x 79
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 = 94694074825/(1x5)
LCM = 94694074825/5
LCM = 18938814965
Thus, we can understand that the LCM of 401,899,665,395 is 18938814965.
