Given numbers are 775,566,394,451,561
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 775,566,394,451,561 is 1987609564050.
Find LCM of 775,566,394,451,561 with Prime Factorization
| 2 | 775, 566, 394, 451, 561 |
| 11 | 775, 283, 197, 451, 561 |
| 775, 283, 197, 41, 51 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 775 x 283 x 197 x 41 x 51 = 1987609564050
Therefore, the lowest common multiple of 775,566,394,451,561 is 1987609564050.
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.
775 x 566 x 394 x 451 x 561 = 43727410409100
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.
775 : 1, 5, 25, 31, 155, 775
566 : 1, 2, 283, 566
394 : 1, 2, 197, 394
451 : 1, 11, 41, 451
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 775,566,394,451,561, is 1.
Now, the common factors can be found like this.
775:5x 5x 31
566:2x 283
394:2x 197
451:11x 41
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.
2x 11 = 22
Therefore, the value for common factors is 22.
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 = 43727410409100/(1x22)
LCM = 43727410409100/22
LCM = 1987609564050
Thus, we can understand that the LCM of 775,566,394,451,561 is 1987609564050.
