Given numbers are 291,241,687,981
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 291,241,687,981 is 5251619673.
Find LCM of 291,241,687,981 with Prime Factorization
| 3 | 291, 241, 687, 981 |
| 97, 241, 229, 327 |
Multiply the prime numbers at the bottom and the left side.
3 x 97 x 241 x 229 x 327 = 5251619673
Therefore, the lowest common multiple of 291,241,687,981 is 5251619673.
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.
291 x 241 x 687 x 981 = 47264577057
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.
291 : 1, 3, 97, 291
241 : 1, 241
687 : 1, 3, 229, 687
981 : 1, 3, 9, 109, 327, 981
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 291,241,687,981, is 1.
Now, the common factors can be found like this.
291:3x 97
241:241
687:3x 229
981:3x 3x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 47264577057/(1x9)
LCM = 47264577057/9
LCM = 5251619673
Thus, we can understand that the LCM of 291,241,687,981 is 5251619673.
