Given numbers are 561,677,998,746
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,677,998,746 is 141380952438.
Find LCM of 561,677,998,746 with Prime Factorization
| 2 | 561, 677, 998, 746 |
| 561, 677, 499, 373 |
Multiply the prime numbers at the bottom and the left side.
2 x 561 x 677 x 499 x 373 = 141380952438
Therefore, the lowest common multiple of 561,677,998,746 is 141380952438.
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 677 x 998 x 746 = 282761904876
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
677 : 1, 677
998 : 1, 2, 499, 998
746 : 1, 2, 373, 746
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,677,998,746, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
677:677
998:2x 499
746:2x 373
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 282761904876/(1x2)
LCM = 282761904876/2
LCM = 141380952438
Thus, we can understand that the LCM of 561,677,998,746 is 141380952438.
