Given numbers are 256,323,663,391
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 256,323,663,391 is 74171136.
Find LCM of 256,323,663,391 with Prime Factorization
17 | 256, 323, 663, 391 |
256, 19, 39, 23 |
Multiply the prime numbers at the bottom and the left side.
17 x 256 x 19 x 39 x 23 = 74171136
Therefore, the lowest common multiple of 256,323,663,391 is 74171136.
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 323 x 663 x 391 = 21435458304
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
323 : 1, 17, 19, 323
663 : 1, 3, 13, 17, 39, 51, 221, 663
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 256,323,663,391, is 1.
Now, the common factors can be found like this.
256:2x 2x 2x 2x 2x 2x 2x 2
323:17x 19
663:3x 13x 17
391:17x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17x 17 = 289
Therefore, the value for common factors is 289.
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 = 21435458304/(1x289)
LCM = 21435458304/289
LCM = 74171136
Thus, we can understand that the LCM of 256,323,663,391 is 74171136.
