Given numbers are 561,738,618,266,105
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,738,618,266,105 is 9452720970.
Find LCM of 561,738,618,266,105 with Prime Factorization
| 2 | 561, 738, 618, 266, 105 |
| 3 | 561, 369, 309, 133, 105 |
| 7 | 187, 123, 103, 133, 35 |
| 187, 123, 103, 19, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 187 x 123 x 103 x 19 x 5 = 9452720970
Therefore, the lowest common multiple of 561,738,618,266,105 is 9452720970.
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.
561 x 738 x 618 x 266 x 105 = 7146257053320
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.
561 : 1, 3, 11, 17, 33, 51, 187, 561
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
618 : 1, 2, 3, 6, 103, 206, 309, 618
266 : 1, 2, 7, 14, 19, 38, 133, 266
105 : 1, 3, 5, 7, 15, 21, 35, 105
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,738,618,266,105, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
738:2x 3x 3x 41
618:2x 3x 103
266:2x 7x 19
105:3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3x 3x 7 = 756
Therefore, the value for common factors is 756.
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 = 7146257053320/(1x756)
LCM = 7146257053320/756
LCM = 9452720970
Thus, we can understand that the LCM of 561,738,618,266,105 is 9452720970.
