Given numbers are 665,591,639,591
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 665,591,639,591 is 83712195.
Find LCM of 665,591,639,591 with Prime Factorization
| 3 | 665, 591, 639, 591 |
| 197 | 665, 197, 213, 197 |
| 665, 1, 213, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 197 x 665 x 1 x 213 x 1 = 83712195
Therefore, the lowest common multiple of 665,591,639,591 is 83712195.
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.
665 x 591 x 639 x 591 = 148421721735
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.
665 : 1, 5, 7, 19, 35, 95, 133, 665
591 : 1, 3, 197, 591
639 : 1, 3, 9, 71, 213, 639
591 : 1, 3, 197, 591
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,591,639,591, is 1.
Now, the common factors can be found like this.
665:5x 7x 19
591:3x 197
639:3x 3x 71
591:3x 197
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 197 = 1773
Therefore, the value for common factors is 1773.
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 = 148421721735/(1x1773)
LCM = 148421721735/1773
LCM = 83712195
Thus, we can understand that the LCM of 665,591,639,591 is 83712195.
