Given numbers are 605,675,949,243
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 605,675,949,243 is 697586175.
Find LCM of 605,675,949,243 with Prime Factorization
3 | 605, 675, 949, 243 |
3 | 605, 225, 949, 81 |
3 | 605, 75, 949, 27 |
5 | 605, 25, 949, 9 |
121, 5, 949, 9 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 5 x 121 x 5 x 949 x 9 = 697586175
Therefore, the lowest common multiple of 605,675,949,243 is 697586175.
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.
605 x 675 x 949 x 243 = 94174133625
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.
605 : 1, 5, 11, 55, 121, 605
675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675
949 : 1, 13, 73, 949
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 605,675,949,243, is 1.
Now, the common factors can be found like this.
605:5x 11x 11
675:3x 3x 3x 5x 5
949:13x 73
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 5 = 135
Therefore, the value for common factors is 135.
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 = 94174133625/(1x135)
LCM = 94174133625/135
LCM = 697586175
Thus, we can understand that the LCM of 605,675,949,243 is 697586175.
