Given numbers are 797,646,966,380,943
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 797,646,966,380,943 is 101958121860.
Find LCM of 797,646,966,380,943 with Prime Factorization
| 2 | 797, 646, 966, 380, 943 |
| 19 | 797, 323, 483, 190, 943 |
| 23 | 797, 17, 483, 10, 943 |
| 797, 17, 21, 10, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 23 x 797 x 17 x 21 x 10 x 41 = 101958121860
Therefore, the lowest common multiple of 797,646,966,380,943 is 101958121860.
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.
797 x 646 x 966 x 380 x 943 = 178222797011280
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.
797 : 1, 797
646 : 1, 2, 17, 19, 34, 38, 323, 646
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
943 : 1, 23, 41, 943
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 797,646,966,380,943, is 1.
Now, the common factors can be found like this.
797:797
646:2x 17x 19
966:2x 3x 7x 23
380:2x 2x 5x 19
943:23x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 19x 23 = 1748
Therefore, the value for common factors is 1748.
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 = 178222797011280/(1x1748)
LCM = 178222797011280/1748
LCM = 101958121860
Thus, we can understand that the LCM of 797,646,966,380,943 is 101958121860.
