Given numbers are 7,561,591,617
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 7,561,591,617 is 477322923.
Find LCM of 7,561,591,617 with Prime Factorization
| 3 | 7, 561, 591, 617 |
| 7, 187, 197, 617 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 187 x 197 x 617 = 477322923
Therefore, the lowest common multiple of 7,561,591,617 is 477322923.
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.
7 x 561 x 591 x 617 = 1431968769
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.
7 : 1, 7
561 : 1, 3, 11, 17, 33, 51, 187, 561
591 : 1, 3, 197, 591
617 : 1, 617
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7,561,591,617, is 1.
Now, the common factors can be found like this.
7:7
561:3x 11x 17
591:3x 197
617:617
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 = 1431968769/(1x3)
LCM = 1431968769/3
LCM = 477322923
Thus, we can understand that the LCM of 7,561,591,617 is 477322923.
