Given numbers are 128,852,954,161
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 128,852,954,161 is 697931136.
Find LCM of 128,852,954,161 with Prime Factorization
2 | 128, 852, 954, 161 |
2 | 64, 426, 477, 161 |
3 | 32, 213, 477, 161 |
32, 71, 159, 161 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 32 x 71 x 159 x 161 = 697931136
Therefore, the lowest common multiple of 128,852,954,161 is 697931136.
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 852 x 954 x 161 = 16750347264
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
852 : 1, 2, 3, 4, 6, 12, 71, 142, 213, 284, 426, 852
954 : 1, 2, 3, 6, 9, 18, 53, 106, 159, 318, 477, 954
161 : 1, 7, 23, 161
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,852,954,161, is 1.
Now, the common factors can be found like this.
128:2x 2x 2x 2x 2x 2x 2
852:2x 2x 3x 71
954:2x 3x 3x 53
161:7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3 = 24
Therefore, the value for common factors is 24.
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 = 16750347264/(1x24)
LCM = 16750347264/24
LCM = 697931136
Thus, we can understand that the LCM of 128,852,954,161 is 697931136.
