Given numbers are 561,689,285,337
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,689,285,337 is 12374725935.
Find LCM of 561,689,285,337 with Prime Factorization
| 3 | 561, 689, 285, 337 |
| 187, 689, 95, 337 |
Multiply the prime numbers at the bottom and the left side.
3 x 187 x 689 x 95 x 337 = 12374725935
Therefore, the lowest common multiple of 561,689,285,337 is 12374725935.
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 689 x 285 x 337 = 37124177805
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
689 : 1, 13, 53, 689
285 : 1, 3, 5, 15, 19, 57, 95, 285
337 : 1, 337
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,689,285,337, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
689:13x 53
285:3x 5x 19
337:337
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 37124177805/(1x3)
LCM = 37124177805/3
LCM = 12374725935
Thus, we can understand that the LCM of 561,689,285,337 is 12374725935.
