Given numbers are 731,319,715,818
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 731,319,715,818 is 12398659130.
Find LCM of 731,319,715,818 with Prime Factorization
| 11 | 731, 319, 715, 818 |
| 731, 29, 65, 818 |
Multiply the prime numbers at the bottom and the left side.
11 x 731 x 29 x 65 x 818 = 12398659130
Therefore, the lowest common multiple of 731,319,715,818 is 12398659130.
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.
731 x 319 x 715 x 818 = 136385250430
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.
731 : 1, 17, 43, 731
319 : 1, 11, 29, 319
715 : 1, 5, 11, 13, 55, 65, 143, 715
818 : 1, 2, 409, 818
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,319,715,818, is 1.
Now, the common factors can be found like this.
731:17x 43
319:11x 29
715:5x 11x 13
818:2x 409
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 136385250430/(1x11)
LCM = 136385250430/11
LCM = 12398659130
Thus, we can understand that the LCM of 731,319,715,818 is 12398659130.
