Given numbers are 781,215,789,935
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,215,789,935 is 2252243895.
Find LCM of 781,215,789,935 with Prime Factorization
5 | 781, 215, 789, 935 |
11 | 781, 43, 789, 187 |
71, 43, 789, 17 |
Multiply the prime numbers at the bottom and the left side.
5 x 11 x 71 x 43 x 789 x 17 = 2252243895
Therefore, the lowest common multiple of 781,215,789,935 is 2252243895.
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 215 x 789 x 935 = 123873414225
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
215 : 1, 5, 43, 215
789 : 1, 3, 263, 789
935 : 1, 5, 11, 17, 55, 85, 187, 935
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,215,789,935, is 1.
Now, the common factors can be found like this.
781:11x 71
215:5x 43
789:3x 263
935:5x 11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 11 = 55
Therefore, the value for common factors is 55.
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 = 123873414225/(1x55)
LCM = 123873414225/55
LCM = 2252243895
Thus, we can understand that the LCM of 781,215,789,935 is 2252243895.
