Given numbers are 401,957,781,481
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 401,957,781,481 is 13105685307.
Find LCM of 401,957,781,481 with Prime Factorization
| 11 | 401, 957, 781, 481 |
| 401, 87, 71, 481 |
Multiply the prime numbers at the bottom and the left side.
11 x 401 x 87 x 71 x 481 = 13105685307
Therefore, the lowest common multiple of 401,957,781,481 is 13105685307.
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 957 x 781 x 481 = 144162538377
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
957 : 1, 3, 11, 29, 33, 87, 319, 957
781 : 1, 11, 71, 781
481 : 1, 13, 37, 481
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 401,957,781,481, is 1.
Now, the common factors can be found like this.
401:401
957:3x 11x 29
781:11x 71
481:13x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 144162538377/(1x11)
LCM = 144162538377/11
LCM = 13105685307
Thus, we can understand that the LCM of 401,957,781,481 is 13105685307.
