Given numbers are 909,985,985,297
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 909,985,985,297 is 29547045.
Find LCM of 909,985,985,297 with Prime Factorization
| 3 | 909, 985, 985, 297 |
| 3 | 303, 985, 985, 99 |
| 5 | 101, 985, 985, 33 |
| 197 | 101, 197, 197, 33 |
| 101, 1, 1, 33 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 197 x 101 x 1 x 1 x 33 = 29547045
Therefore, the lowest common multiple of 909,985,985,297 is 29547045.
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.
909 x 985 x 985 x 297 = 261934553925
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.
909 : 1, 3, 9, 101, 303, 909
985 : 1, 5, 197, 985
985 : 1, 5, 197, 985
297 : 1, 3, 9, 11, 27, 33, 99, 297
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 909,985,985,297, is 1.
Now, the common factors can be found like this.
909:3x 3x 101
985:5x 197
985:5x 197
297:3x 3x 3x 11
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 5x 197 = 8865
Therefore, the value for common factors is 8865.
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 = 261934553925/(1x8865)
LCM = 261934553925/8865
LCM = 29547045
Thus, we can understand that the LCM of 909,985,985,297 is 29547045.
