Given numbers are 818,457,656,457
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 818,457,656,457 is 122614928.
Find LCM of 818,457,656,457 with Prime Factorization
2 | 818, 457, 656, 457 |
457 | 409, 457, 328, 457 |
409, 1, 328, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 457 x 409 x 1 x 328 x 1 = 122614928
Therefore, the lowest common multiple of 818,457,656,457 is 122614928.
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.
818 x 457 x 656 x 457 = 112070044192
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.
818 : 1, 2, 409, 818
457 : 1, 457
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
457 : 1, 457
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 818,457,656,457, is 1.
Now, the common factors can be found like this.
818:2x 409
457:457
656:2x 2x 2x 2x 41
457:457
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 457 = 914
Therefore, the value for common factors is 914.
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 = 112070044192/(1x914)
LCM = 112070044192/914
LCM = 122614928
Thus, we can understand that the LCM of 818,457,656,457 is 122614928.
