Given numbers are 407,986,781,305
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 407,986,781,305 is 8690194810.
Find LCM of 407,986,781,305 with Prime Factorization
11 | 407, 986, 781, 305 |
37, 986, 71, 305 |
Multiply the prime numbers at the bottom and the left side.
11 x 37 x 986 x 71 x 305 = 8690194810
Therefore, the lowest common multiple of 407,986,781,305 is 8690194810.
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.
407 x 986 x 781 x 305 = 95592142910
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.
407 : 1, 11, 37, 407
986 : 1, 2, 17, 29, 34, 58, 493, 986
781 : 1, 11, 71, 781
305 : 1, 5, 61, 305
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 407,986,781,305, is 1.
Now, the common factors can be found like this.
407:11x 37
986:2x 17x 29
781:11x 71
305:5x 61
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 = 95592142910/(1x11)
LCM = 95592142910/11
LCM = 8690194810
Thus, we can understand that the LCM of 407,986,781,305 is 8690194810.
