Given numbers are 808,781,187,861
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 808,781,187,861 is 9236649576.
Find LCM of 808,781,187,861 with Prime Factorization
11 | 808, 781, 187, 861 |
808, 71, 17, 861 |
Multiply the prime numbers at the bottom and the left side.
11 x 808 x 71 x 17 x 861 = 9236649576
Therefore, the lowest common multiple of 808,781,187,861 is 9236649576.
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.
808 x 781 x 187 x 861 = 101603145336
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.
808 : 1, 2, 4, 8, 101, 202, 404, 808
781 : 1, 11, 71, 781
187 : 1, 11, 17, 187
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 808,781,187,861, is 1.
Now, the common factors can be found like this.
808:2x 2x 2x 101
781:11x 71
187:11x 17
861:3x 7x 41
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 = 101603145336/(1x11)
LCM = 101603145336/11
LCM = 9236649576
Thus, we can understand that the LCM of 808,781,187,861 is 9236649576.
