Given numbers are 128,645,653,993
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 128,645,653,993 is 17844766080.
Find LCM of 128,645,653,993 with Prime Factorization
3 | 128, 645, 653, 993 |
128, 215, 653, 331 |
Multiply the prime numbers at the bottom and the left side.
3 x 128 x 215 x 653 x 331 = 17844766080
Therefore, the lowest common multiple of 128,645,653,993 is 17844766080.
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.
128 x 645 x 653 x 993 = 53534298240
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.
128 : 1, 2, 4, 8, 16, 32, 64, 128
645 : 1, 3, 5, 15, 43, 129, 215, 645
653 : 1, 653
993 : 1, 3, 331, 993
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,645,653,993, is 1.
Now, the common factors can be found like this.
128:2x 2x 2x 2x 2x 2x 2
645:3x 5x 43
653:653
993:3x 331
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 = 53534298240/(1x3)
LCM = 53534298240/3
LCM = 17844766080
Thus, we can understand that the LCM of 128,645,653,993 is 17844766080.
