Given numbers are 158,268,912,928
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 158,268,912,928 is 279978528.
Find LCM of 158,268,912,928 with Prime Factorization
| 2 | 158, 268, 912, 928 |
| 2 | 79, 134, 456, 464 |
| 2 | 79, 67, 228, 232 |
| 2 | 79, 67, 114, 116 |
| 79, 67, 57, 58 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 79 x 67 x 57 x 58 = 279978528
Therefore, the lowest common multiple of 158,268,912,928 is 279978528.
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.
158 x 268 x 912 x 928 = 35837251584
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.
158 : 1, 2, 79, 158
268 : 1, 2, 4, 67, 134, 268
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 158,268,912,928, is 2.
Now, the common factors can be found like this.
158:2x 79
268:2x 2x 67
912:2x 2x 2x 2x 3x 19
928:2x 2x 2x 2x 2x 29
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 2 = 64
Therefore, the value for common factors is 64.
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 = 35837251584/(2x64)
LCM = 35837251584/128
LCM = 279978528
Thus, we can understand that the LCM of 158,268,912,928 is 279978528.
