Given numbers are 401,921,338,923
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 401,921,338,923 is 8862965358.
Find LCM of 401,921,338,923 with Prime Factorization
13 | 401, 921, 338, 923 |
401, 921, 26, 71 |
Multiply the prime numbers at the bottom and the left side.
13 x 401 x 921 x 26 x 71 = 8862965358
Therefore, the lowest common multiple of 401,921,338,923 is 8862965358.
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 921 x 338 x 923 = 115218549654
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
921 : 1, 3, 307, 921
338 : 1, 2, 13, 26, 169, 338
923 : 1, 13, 71, 923
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 401,921,338,923, is 1.
Now, the common factors can be found like this.
401:401
921:3x 307
338:2x 13x 13
923:13x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13 = 13
Therefore, the value for common factors is 13.
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 = 115218549654/(1x13)
LCM = 115218549654/13
LCM = 8862965358
Thus, we can understand that the LCM of 401,921,338,923 is 8862965358.
