Given numbers are 128,289,394,315
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 128,289,394,315 is 2295538560.
Find LCM of 128,289,394,315 with Prime Factorization
2 | 128, 289, 394, 315 |
64, 289, 197, 315 |
Multiply the prime numbers at the bottom and the left side.
2 x 64 x 289 x 197 x 315 = 2295538560
Therefore, the lowest common multiple of 128,289,394,315 is 2295538560.
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 289 x 394 x 315 = 4591077120
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
289 : 1, 17, 289
394 : 1, 2, 197, 394
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,289,394,315, is 1.
Now, the common factors can be found like this.
128:2x 2x 2x 2x 2x 2x 2
289:17x 17
394:2x 197
315:3x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 4591077120/(1x2)
LCM = 4591077120/2
LCM = 2295538560
Thus, we can understand that the LCM of 128,289,394,315 is 2295538560.
