Given numbers are 347,909,162,243
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 347,909,162,243 is 17032842.
Find LCM of 347,909,162,243 with Prime Factorization
| 3 | 347, 909, 162, 243 |
| 3 | 347, 303, 54, 81 |
| 3 | 347, 101, 18, 27 |
| 3 | 347, 101, 6, 9 |
| 347, 101, 2, 3 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 3 x 347 x 101 x 2 x 3 = 17032842
Therefore, the lowest common multiple of 347,909,162,243 is 17032842.
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.
347 x 909 x 162 x 243 = 12416941818
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.
347 : 1, 347
909 : 1, 3, 9, 101, 303, 909
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
243 : 1, 3, 9, 27, 81, 243
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 347,909,162,243, is 1.
Now, the common factors can be found like this.
347:347
909:3x 3x 101
162:2x 3x 3x 3x 3
243:3x 3x 3x 3x 3
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 3x 3x 3 = 729
Therefore, the value for common factors is 729.
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 = 12416941818/(1x729)
LCM = 12416941818/729
LCM = 17032842
Thus, we can understand that the LCM of 347,909,162,243 is 17032842.
