Given numbers are 867,836,615,517,407
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 867,836,615,517,407 is 258391853940.
Find LCM of 867,836,615,517,407 with Prime Factorization
| 3 | 867, 836, 615, 517, 407 |
| 11 | 289, 836, 205, 517, 407 |
| 289, 76, 205, 47, 37 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 289 x 76 x 205 x 47 x 37 = 258391853940
Therefore, the lowest common multiple of 867,836,615,517,407 is 258391853940.
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.
867 x 836 x 615 x 517 x 407 = 93796242980220
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.
867 : 1, 3, 17, 51, 289, 867
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
615 : 1, 3, 5, 15, 41, 123, 205, 615
517 : 1, 11, 47, 517
407 : 1, 11, 37, 407
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 867,836,615,517,407, is 1.
Now, the common factors can be found like this.
867:3x 17x 17
836:2x 2x 11x 19
615:3x 5x 41
517:11x 47
407:11x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 11 = 363
Therefore, the value for common factors is 363.
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 = 93796242980220/(1x363)
LCM = 93796242980220/363
LCM = 258391853940
Thus, we can understand that the LCM of 867,836,615,517,407 is 258391853940.
