Given numbers are 768,835,899,921
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 768,835,899,921 is 176988791040.
Find LCM of 768,835,899,921 with Prime Factorization
3 | 768, 835, 899, 921 |
256, 835, 899, 307 |
Multiply the prime numbers at the bottom and the left side.
3 x 256 x 835 x 899 x 307 = 176988791040
Therefore, the lowest common multiple of 768,835,899,921 is 176988791040.
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.
768 x 835 x 899 x 921 = 530966373120
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.
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
835 : 1, 5, 167, 835
899 : 1, 29, 31, 899
921 : 1, 3, 307, 921
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 768,835,899,921, is 1.
Now, the common factors can be found like this.
768:2x 2x 2x 2x 2x 2x 2x 2x 3
835:5x 167
899:29x 31
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.
3 = 3
Therefore, the value for common factors is 3.
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 = 530966373120/(1x3)
LCM = 530966373120/3
LCM = 176988791040
Thus, we can understand that the LCM of 768,835,899,921 is 176988791040.
