Given numbers are 891,154,797,920
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 891,154,797,920 is 4573217880.
Find LCM of 891,154,797,920 with Prime Factorization
2 | 891, 154, 797, 920 |
11 | 891, 77, 797, 460 |
81, 7, 797, 460 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 81 x 7 x 797 x 460 = 4573217880
Therefore, the lowest common multiple of 891,154,797,920 is 4573217880.
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.
891 x 154 x 797 x 920 = 100610793360
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.
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
154 : 1, 2, 7, 11, 14, 22, 77, 154
797 : 1, 797
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 891,154,797,920, is 1.
Now, the common factors can be found like this.
891:3x 3x 3x 3x 11
154:2x 7x 11
797:797
920:2x 2x 2x 5x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11 = 22
Therefore, the value for common factors is 22.
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 = 100610793360/(1x22)
LCM = 100610793360/22
LCM = 4573217880
Thus, we can understand that the LCM of 891,154,797,920 is 4573217880.
