Given numbers are 681,538,668,241
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 681,538,668,241 is 29491230732.
Find LCM of 681,538,668,241 with Prime Factorization
2 | 681, 538, 668, 241 |
681, 269, 334, 241 |
Multiply the prime numbers at the bottom and the left side.
2 x 681 x 269 x 334 x 241 = 29491230732
Therefore, the lowest common multiple of 681,538,668,241 is 29491230732.
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 538 x 668 x 241 = 58982461464
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
538 : 1, 2, 269, 538
668 : 1, 2, 4, 167, 334, 668
241 : 1, 241
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,538,668,241, is 1.
Now, the common factors can be found like this.
681:3x 227
538:2x 269
668:2x 2x 167
241:241
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 = 58982461464/(1x2)
LCM = 58982461464/2
LCM = 29491230732
Thus, we can understand that the LCM of 681,538,668,241 is 29491230732.
