Given numbers are 297,727,554,561
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 297,727,554,561 is 2033525142.
Find LCM of 297,727,554,561 with Prime Factorization
| 3 | 297, 727, 554, 561 |
| 11 | 99, 727, 554, 187 |
| 9, 727, 554, 17 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 9 x 727 x 554 x 17 = 2033525142
Therefore, the lowest common multiple of 297,727,554,561 is 2033525142.
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.
297 x 727 x 554 x 561 = 67106329686
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.
297 : 1, 3, 9, 11, 27, 33, 99, 297
727 : 1, 727
554 : 1, 2, 277, 554
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 297,727,554,561, is 1.
Now, the common factors can be found like this.
297:3x 3x 3x 11
727:727
554:2x 277
561:3x 11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11 = 33
Therefore, the value for common factors is 33.
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 = 67106329686/(1x33)
LCM = 67106329686/33
LCM = 2033525142
Thus, we can understand that the LCM of 297,727,554,561 is 2033525142.
