Given numbers are 679,841,841,729
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 679,841,841,729 is 416287431.
Find LCM of 679,841,841,729 with Prime Factorization
29 | 679, 841, 841, 729 |
29 | 679, 29, 29, 729 |
679, 1, 1, 729 |
Multiply the prime numbers at the bottom and the left side.
29 x 29 x 679 x 1 x 1 x 729 = 416287431
Therefore, the lowest common multiple of 679,841,841,729 is 416287431.
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.
679 x 841 x 841 x 729 = 350097729471
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.
679 : 1, 7, 97, 679
841 : 1, 29, 841
841 : 1, 29, 841
729 : 1, 3, 9, 27, 81, 243, 729
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 679,841,841,729, is 1.
Now, the common factors can be found like this.
679:7x 97
841:29x 29
841:29x 29
729:3x 3x 3x 3x 3x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
29x 29 = 841
Therefore, the value for common factors is 841.
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 = 350097729471/(1x841)
LCM = 350097729471/841
LCM = 416287431
Thus, we can understand that the LCM of 679,841,841,729 is 416287431.
