Find LCM of 144,979,928,122,128 with Prime Factorization
| 2 | 144, 979, 928, 122, 128 |
| 2 | 72, 979, 464, 61, 64 |
| 2 | 36, 979, 232, 61, 32 |
| 2 | 18, 979, 116, 61, 16 |
| 2 | 9, 979, 58, 61, 8 |
| 9, 979, 29, 61, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 9 x 979 x 29 x 61 x 4 = 1995092352
Therefore, the lowest common multiple of 144,979,928,122,128 is 1995092352.
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.
144 x 979 x 928 x 122 x 128 = 2042974568448
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.
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
979 : 1, 11, 89, 979
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
122 : 1, 2, 61, 122
128 : 1, 2, 4, 8, 16, 32, 64, 128
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 144,979,928,122,128, is 1.
Now, the common factors can be found like this.
144:2x 2x 2x 2x 3x 3
979:11x 89
928:2x 2x 2x 2x 2x 29
122:2x 61
128:2x 2x 2x 2x 2x 2x 2
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 2x 2x 2x 2x 2x 2x 2 = 1024
Therefore, the value for common factors is 1024.
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 = 2042974568448/(1x1024)
LCM = 2042974568448/1024
LCM = 1995092352
Thus, we can understand that the LCM of 144,979,928,122,128 is 1995092352.
