Find LCM of 561,809,457,374,180 with Prime Factorization
| 2 | 561, 809, 457, 374, 180 |
| 3 | 561, 809, 457, 187, 90 |
| 11 | 187, 809, 457, 187, 30 |
| 17 | 17, 809, 457, 17, 30 |
| 1, 809, 457, 1, 30 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 17 x 1 x 809 x 457 x 1 x 30 = 12444539580
Therefore, the lowest common multiple of 561,809,457,374,180 is 12444539580.
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 809 x 457 x 374 x 180 = 13962773408760
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
809 : 1, 809
457 : 1, 457
374 : 1, 2, 11, 17, 22, 34, 187, 374
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,809,457,374,180, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
809:809
457:457
374:2x 11x 17
180:2x 2x 3x 3x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 11x 17 = 1122
Therefore, the value for common factors is 1122.
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 = 13962773408760/(1x1122)
LCM = 13962773408760/1122
LCM = 12444539580
Thus, we can understand that the LCM of 561,809,457,374,180 is 12444539580.
