Given numbers are 755,473,891,731
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 755,473,891,731 is 491747355.
Find LCM of 755,473,891,731 with Prime Factorization
11 | 755, 473, 891, 731 |
43 | 755, 43, 81, 731 |
755, 1, 81, 17 |
Multiply the prime numbers at the bottom and the left side.
11 x 43 x 755 x 1 x 81 x 17 = 491747355
Therefore, the lowest common multiple of 755,473,891,731 is 491747355.
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.
755 x 473 x 891 x 731 = 232596498915
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.
755 : 1, 5, 151, 755
473 : 1, 11, 43, 473
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
731 : 1, 17, 43, 731
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 755,473,891,731, is 1.
Now, the common factors can be found like this.
755:5x 151
473:11x 43
891:3x 3x 3x 3x 11
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.
11x 43 = 473
Therefore, the value for common factors is 473.
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 = 232596498915/(1x473)
LCM = 232596498915/473
LCM = 491747355
Thus, we can understand that the LCM of 755,473,891,731 is 491747355.
