Given numbers are 931,561,418,775
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 931,561,418,775 is 809551050.
Find LCM of 931,561,418,775 with Prime Factorization
| 11 | 931, 561, 418, 775 |
| 19 | 931, 51, 38, 775 |
| 49, 51, 2, 775 |
Multiply the prime numbers at the bottom and the left side.
11 x 19 x 49 x 51 x 2 x 775 = 809551050
Therefore, the lowest common multiple of 931,561,418,775 is 809551050.
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.
931 x 561 x 418 x 775 = 169196169450
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.
931 : 1, 7, 19, 49, 133, 931
561 : 1, 3, 11, 17, 33, 51, 187, 561
418 : 1, 2, 11, 19, 22, 38, 209, 418
775 : 1, 5, 25, 31, 155, 775
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 931,561,418,775, is 1.
Now, the common factors can be found like this.
931:7x 7x 19
561:3x 11x 17
418:2x 11x 19
775:5x 5x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 19 = 209
Therefore, the value for common factors is 209.
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 = 169196169450/(1x209)
LCM = 169196169450/209
LCM = 809551050
Thus, we can understand that the LCM of 931,561,418,775 is 809551050.
