Given numbers are 681,958,681,591
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 681,958,681,591 is 128522406.
Find LCM of 681,958,681,591 with Prime Factorization
| 3 | 681, 958, 681, 591 |
| 227 | 227, 958, 227, 197 |
| 1, 958, 1, 197 |
Multiply the prime numbers at the bottom and the left side.
3 x 227 x 1 x 958 x 1 x 197 = 128522406
Therefore, the lowest common multiple of 681,958,681,591 is 128522406.
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.
681 x 958 x 681 x 591 = 262571275458
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.
681 : 1, 3, 227, 681
958 : 1, 2, 479, 958
681 : 1, 3, 227, 681
591 : 1, 3, 197, 591
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,958,681,591, is 1.
Now, the common factors can be found like this.
681:3x 227
958:2x 479
681:3x 227
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 227 = 2043
Therefore, the value for common factors is 2043.
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 = 262571275458/(1x2043)
LCM = 262571275458/2043
LCM = 128522406
Thus, we can understand that the LCM of 681,958,681,591 is 128522406.
