Given numbers are 213,675,729,851
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 213,675,729,851 is 1101172725.
Find LCM of 213,675,729,851 with Prime Factorization
| 3 | 213, 675, 729, 851 |
| 3 | 71, 225, 243, 851 |
| 3 | 71, 75, 81, 851 |
| 71, 25, 27, 851 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 71 x 25 x 27 x 851 = 1101172725
Therefore, the lowest common multiple of 213,675,729,851 is 1101172725.
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 675 x 729 x 851 = 89194990725
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
675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675
729 : 1, 3, 9, 27, 81, 243, 729
851 : 1, 23, 37, 851
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 213,675,729,851, is 1.
Now, the common factors can be found like this.
213:3x 71
675:3x 3x 3x 5x 5
729:3x 3x 3x 3x 3x 3
851:23x 37
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 3 = 81
Therefore, the value for common factors is 81.
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 = 89194990725/(1x81)
LCM = 89194990725/81
LCM = 1101172725
Thus, we can understand that the LCM of 213,675,729,851 is 1101172725.
