Find LCM of 561,935,866,855,731 with Prime Factorization
| 3 | 561, 935, 866, 855, 731 |
| 5 | 187, 935, 866, 285, 731 |
| 11 | 187, 187, 866, 57, 731 |
| 17 | 17, 17, 866, 57, 731 |
| 1, 1, 866, 57, 43 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 17 x 1 x 1 x 866 x 57 x 43 = 5953797630
Therefore, the lowest common multiple of 561,935,866,855,731 is 5953797630.
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 935 x 866 x 855 x 731 = 283906839986550
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
935 : 1, 5, 11, 17, 55, 85, 187, 935
866 : 1, 2, 433, 866
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
731 : 1, 17, 43, 731
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,935,866,855,731, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
935:5x 11x 17
866:2x 433
855:3x 3x 5x 19
731:17x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 11x 17x 17 = 47685
Therefore, the value for common factors is 47685.
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 = 283906839986550/(1x47685)
LCM = 283906839986550/47685
LCM = 5953797630
Thus, we can understand that the LCM of 561,935,866,855,731 is 5953797630.
