Given numbers are 271,813,615,787,987
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 271,813,615,787,987 is 43153401795.
Find LCM of 271,813,615,787,987 with Prime Factorization
| 3 | 271, 813, 615, 787, 987 |
| 271 | 271, 271, 205, 787, 329 |
| 1, 1, 205, 787, 329 |
Multiply the prime numbers at the bottom and the left side.
3 x 271 x 1 x 1 x 205 x 787 x 329 = 43153401795
Therefore, the lowest common multiple of 271,813,615,787,987 is 43153401795.
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.
271 x 813 x 615 x 787 x 987 = 105251146978005
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.
271 : 1, 271
813 : 1, 3, 271, 813
615 : 1, 3, 5, 15, 41, 123, 205, 615
787 : 1, 787
987 : 1, 3, 7, 21, 47, 141, 329, 987
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 271,813,615,787,987, is 1.
Now, the common factors can be found like this.
271:271
813:3x 271
615:3x 5x 41
787:787
987:3x 7x 47
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 271 = 2439
Therefore, the value for common factors is 2439.
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 = 105251146978005/(1x2439)
LCM = 105251146978005/2439
LCM = 43153401795
Thus, we can understand that the LCM of 271,813,615,787,987 is 43153401795.
