Given numbers are 811,665,811,657
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 811,665,811,657 is 354329955.
Find LCM of 811,665,811,657 with Prime Factorization
811 | 811, 665, 811, 657 |
1, 665, 1, 657 |
Multiply the prime numbers at the bottom and the left side.
811 x 1 x 665 x 1 x 657 = 354329955
Therefore, the lowest common multiple of 811,665,811,657 is 354329955.
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.
811 x 665 x 811 x 657 = 287361593505
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.
811 : 1, 811
665 : 1, 5, 7, 19, 35, 95, 133, 665
811 : 1, 811
657 : 1, 3, 9, 73, 219, 657
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 811,665,811,657, is 1.
Now, the common factors can be found like this.
811:811
665:5x 7x 19
811:811
657:3x 3x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
811 = 811
Therefore, the value for common factors is 811.
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 = 287361593505/(1x811)
LCM = 287361593505/811
LCM = 354329955
Thus, we can understand that the LCM of 811,665,811,657 is 354329955.
