Given numbers are 213,489,561,431
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 213,489,561,431 is 2798247243.
Find LCM of 213,489,561,431 with Prime Factorization
| 3 | 213, 489, 561, 431 |
| 71, 163, 187, 431 |
Multiply the prime numbers at the bottom and the left side.
3 x 71 x 163 x 187 x 431 = 2798247243
Therefore, the lowest common multiple of 213,489,561,431 is 2798247243.
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.
213 x 489 x 561 x 431 = 25184225187
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.
213 : 1, 3, 71, 213
489 : 1, 3, 163, 489
561 : 1, 3, 11, 17, 33, 51, 187, 561
431 : 1, 431
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 213,489,561,431, is 1.
Now, the common factors can be found like this.
213:3x 71
489:3x 163
561:3x 11x 17
431:431
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 25184225187/(1x9)
LCM = 25184225187/9
LCM = 2798247243
Thus, we can understand that the LCM of 213,489,561,431 is 2798247243.
