Given numbers are 343,317,765,731
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 343,317,765,731 is 3576706245.
Find LCM of 343,317,765,731 with Prime Factorization
17 | 343, 317, 765, 731 |
343, 317, 45, 43 |
Multiply the prime numbers at the bottom and the left side.
17 x 343 x 317 x 45 x 43 = 3576706245
Therefore, the lowest common multiple of 343,317,765,731 is 3576706245.
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.
343 x 317 x 765 x 731 = 60804006165
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.
343 : 1, 7, 49, 343
317 : 1, 317
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
731 : 1, 17, 43, 731
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 343,317,765,731, is 1.
Now, the common factors can be found like this.
343:7x 7x 7
317:317
765:3x 3x 5x 17
731:17x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17 = 17
Therefore, the value for common factors is 17.
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 = 60804006165/(1x17)
LCM = 60804006165/17
LCM = 3576706245
Thus, we can understand that the LCM of 343,317,765,731 is 3576706245.
