Given numbers are 256,455,363,121
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 256,455,363,121 is 42282240.
Find LCM of 256,455,363,121 with Prime Factorization
11 | 256, 455, 363, 121 |
11 | 256, 455, 33, 11 |
256, 455, 3, 1 |
Multiply the prime numbers at the bottom and the left side.
11 x 11 x 256 x 455 x 3 x 1 = 42282240
Therefore, the lowest common multiple of 256,455,363,121 is 42282240.
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.
256 x 455 x 363 x 121 = 5116151040
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.
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
455 : 1, 5, 7, 13, 35, 65, 91, 455
363 : 1, 3, 11, 33, 121, 363
121 : 1, 11, 121
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 256,455,363,121, is 1.
Now, the common factors can be found like this.
256:2x 2x 2x 2x 2x 2x 2x 2
455:5x 7x 13
363:3x 11x 11
121:11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 11 = 121
Therefore, the value for common factors is 121.
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 = 5116151040/(1x121)
LCM = 5116151040/121
LCM = 42282240
Thus, we can understand that the LCM of 256,455,363,121 is 42282240.
