Given numbers are 231,391,512,759
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 231,391,512,759 is 46244352.
Find LCM of 231,391,512,759 with Prime Factorization
| 3 | 231, 391, 512, 759 |
| 11 | 77, 391, 512, 253 |
| 23 | 7, 391, 512, 23 |
| 7, 17, 512, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 23 x 7 x 17 x 512 x 1 = 46244352
Therefore, the lowest common multiple of 231,391,512,759 is 46244352.
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.
231 x 391 x 512 x 759 = 35099463168
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.
231 : 1, 3, 7, 11, 21, 33, 77, 231
391 : 1, 17, 23, 391
512 : 1, 2, 4, 8, 16, 32, 64, 128, 256, 512
759 : 1, 3, 11, 23, 33, 69, 253, 759
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 231,391,512,759, is 1.
Now, the common factors can be found like this.
231:3x 7x 11
391:17x 23
512:2x 2x 2x 2x 2x 2x 2x 2x 2
759:3x 11x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 23 = 759
Therefore, the value for common factors is 759.
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 = 35099463168/(1x759)
LCM = 35099463168/759
LCM = 46244352
Thus, we can understand that the LCM of 231,391,512,759 is 46244352.
