Given numbers are 561,542,995,815
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,542,995,815 is 49314295470.
Find LCM of 561,542,995,815 with Prime Factorization
| 5 | 561, 542, 995, 815 |
| 561, 542, 199, 163 |
Multiply the prime numbers at the bottom and the left side.
5 x 561 x 542 x 199 x 163 = 49314295470
Therefore, the lowest common multiple of 561,542,995,815 is 49314295470.
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 542 x 995 x 815 = 246571477350
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
542 : 1, 2, 271, 542
995 : 1, 5, 199, 995
815 : 1, 5, 163, 815
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,542,995,815, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
542:2x 271
995:5x 199
815:5x 163
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
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 = 246571477350/(1x5)
LCM = 246571477350/5
LCM = 49314295470
Thus, we can understand that the LCM of 561,542,995,815 is 49314295470.
