Given numbers are 869,712,781,891
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 869,712,781,891 is 3558304728.
Find LCM of 869,712,781,891 with Prime Factorization
11 | 869, 712, 781, 891 |
79, 712, 71, 81 |
Multiply the prime numbers at the bottom and the left side.
11 x 79 x 712 x 71 x 81 = 3558304728
Therefore, the lowest common multiple of 869,712,781,891 is 3558304728.
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.
869 x 712 x 781 x 891 = 430554872088
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.
869 : 1, 11, 79, 869
712 : 1, 2, 4, 8, 89, 178, 356, 712
781 : 1, 11, 71, 781
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 869,712,781,891, is 1.
Now, the common factors can be found like this.
869:11x 79
712:2x 2x 2x 89
781:11x 71
891:3x 3x 3x 3x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 11 = 121
Therefore, the value for common factors is 121.
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 = 430554872088/(1x121)
LCM = 430554872088/121
LCM = 3558304728
Thus, we can understand that the LCM of 869,712,781,891 is 3558304728.
