Given numbers are 891,994,964,968,842
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 891,994,964,968,842 is 3953810981736.
Find LCM of 891,994,964,968,842 with Prime Factorization
| 2 | 891, 994, 964, 968, 842 |
| 2 | 891, 497, 482, 484, 421 |
| 11 | 891, 497, 241, 242, 421 |
| 81, 497, 241, 22, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 81 x 497 x 241 x 22 x 421 = 3953810981736
Therefore, the lowest common multiple of 891,994,964,968,842 is 3953810981736.
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 994 x 964 x 968 x 842 = 695870732785536
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
994 : 1, 2, 7, 14, 71, 142, 497, 994
964 : 1, 2, 4, 241, 482, 964
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
842 : 1, 2, 421, 842
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 891,994,964,968,842, is 1.
Now, the common factors can be found like this.
891:3x 3x 3x 3x 11
994:2x 7x 71
964:2x 2x 241
968:2x 2x 2x 11x 11
842:2x 421
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 2x 2x 11 = 176
Therefore, the value for common factors is 176.
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 = 695870732785536/(1x176)
LCM = 695870732785536/176
LCM = 3953810981736
Thus, we can understand that the LCM of 891,994,964,968,842 is 3953810981736.
