Given numbers are 681,681,548,212
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 681,681,548,212 is 19778964.
Find LCM of 681,681,548,212 with Prime Factorization
| 2 | 681, 681, 548, 212 |
| 2 | 681, 681, 274, 106 |
| 3 | 681, 681, 137, 53 |
| 227 | 227, 227, 137, 53 |
| 1, 1, 137, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 227 x 1 x 1 x 137 x 53 = 19778964
Therefore, the lowest common multiple of 681,681,548,212 is 19778964.
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 681 x 548 x 212 = 53877897936
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
681 : 1, 3, 227, 681
548 : 1, 2, 4, 137, 274, 548
212 : 1, 2, 4, 53, 106, 212
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,681,548,212, is 1.
Now, the common factors can be found like this.
681:3x 227
681:3x 227
548:2x 2x 137
212:2x 2x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 227 = 2724
Therefore, the value for common factors is 2724.
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 = 53877897936/(1x2724)
LCM = 53877897936/2724
LCM = 19778964
Thus, we can understand that the LCM of 681,681,548,212 is 19778964.
