Given numbers are 231,407,671,471
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 231,407,671,471 is 81854619.
Find LCM of 231,407,671,471 with Prime Factorization
| 3 | 231, 407, 671, 471 |
| 11 | 77, 407, 671, 157 |
| 7, 37, 61, 157 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 7 x 37 x 61 x 157 = 81854619
Therefore, the lowest common multiple of 231,407,671,471 is 81854619.
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 407 x 671 x 471 = 29713226697
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
407 : 1, 11, 37, 407
671 : 1, 11, 61, 671
471 : 1, 3, 157, 471
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 231,407,671,471, is 1.
Now, the common factors can be found like this.
231:3x 7x 11
407:11x 37
671:11x 61
471:3x 157
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 11 = 363
Therefore, the value for common factors is 363.
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 = 29713226697/(1x363)
LCM = 29713226697/363
LCM = 81854619
Thus, we can understand that the LCM of 231,407,671,471 is 81854619.
