Given numbers are 864,841,442,921
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 864,841,442,921 is 49299258528.
Find LCM of 864,841,442,921 with Prime Factorization
2 | 864, 841, 442, 921 |
3 | 432, 841, 221, 921 |
144, 841, 221, 307 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 144 x 841 x 221 x 307 = 49299258528
Therefore, the lowest common multiple of 864,841,442,921 is 49299258528.
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.
864 x 841 x 442 x 921 = 295795551168
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.
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
841 : 1, 29, 841
442 : 1, 2, 13, 17, 26, 34, 221, 442
921 : 1, 3, 307, 921
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 864,841,442,921, is 1.
Now, the common factors can be found like this.
864:2x 2x 2x 2x 2x 3x 3x 3
841:29x 29
442:2x 13x 17
921:3x 307
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 295795551168/(1x6)
LCM = 295795551168/6
LCM = 49299258528
Thus, we can understand that the LCM of 864,841,442,921 is 49299258528.
