Given numbers are 231,579,741,969,388
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 231,579,741,969,388 is 72635158596.
Find LCM of 231,579,741,969,388 with Prime Factorization
| 3 | 231, 579, 741, 969, 388 |
| 19 | 77, 193, 247, 323, 388 |
| 77, 193, 13, 17, 388 |
Multiply the prime numbers at the bottom and the left side.
3 x 19 x 77 x 193 x 13 x 17 x 388 = 72635158596
Therefore, the lowest common multiple of 231,579,741,969,388 is 72635158596.
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 579 x 741 x 969 x 388 = 37261836359748
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
579 : 1, 3, 193, 579
741 : 1, 3, 13, 19, 39, 57, 247, 741
969 : 1, 3, 17, 19, 51, 57, 323, 969
388 : 1, 2, 4, 97, 194, 388
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 231,579,741,969,388, is 1.
Now, the common factors can be found like this.
231:3x 7x 11
579:3x 193
741:3x 13x 19
969:3x 17x 19
388:2x 2x 97
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 19 = 513
Therefore, the value for common factors is 513.
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 = 37261836359748/(1x513)
LCM = 37261836359748/513
LCM = 72635158596
Thus, we can understand that the LCM of 231,579,741,969,388 is 72635158596.
