Given numbers are 781,731,431,986
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,731,431,986 is 14271633178.
Find LCM of 781,731,431,986 with Prime Factorization
17 | 781, 731, 431, 986 |
781, 43, 431, 58 |
Multiply the prime numbers at the bottom and the left side.
17 x 781 x 43 x 431 x 58 = 14271633178
Therefore, the lowest common multiple of 781,731,431,986 is 14271633178.
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.
781 x 731 x 431 x 986 = 242617764026
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.
781 : 1, 11, 71, 781
731 : 1, 17, 43, 731
431 : 1, 431
986 : 1, 2, 17, 29, 34, 58, 493, 986
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,731,431,986, is 1.
Now, the common factors can be found like this.
781:11x 71
731:17x 43
431:431
986:2x 17x 29
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 = 242617764026/(1x17)
LCM = 242617764026/17
LCM = 14271633178
Thus, we can understand that the LCM of 781,731,431,986 is 14271633178.
