Given numbers are 256,438,764,754,424
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 256,438,764,754,424 is 213961023744.
Find LCM of 256,438,764,754,424 with Prime Factorization
| 2 | 256, 438, 764, 754, 424 |
| 2 | 128, 219, 382, 377, 212 |
| 2 | 64, 219, 191, 377, 106 |
| 32, 219, 191, 377, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 32 x 219 x 191 x 377 x 53 = 213961023744
Therefore, the lowest common multiple of 256,438,764,754,424 is 213961023744.
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 438 x 764 x 754 x 424 = 27387011039232
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
438 : 1, 2, 3, 6, 73, 146, 219, 438
764 : 1, 2, 4, 191, 382, 764
754 : 1, 2, 13, 26, 29, 58, 377, 754
424 : 1, 2, 4, 8, 53, 106, 212, 424
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 256,438,764,754,424, is 2.
Now, the common factors can be found like this.
256:2x 2x 2x 2x 2x 2x 2x 2
438:2x 3x 73
764:2x 2x 191
754:2x 13x 29
424:2x 2x 2x 53
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 = 27387011039232/(2x64)
LCM = 27387011039232/128
LCM = 213961023744
Thus, we can understand that the LCM of 256,438,764,754,424 is 213961023744.
