Given numbers are 897,403,991,261
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 897,403,991,261 is 2397436119.
Find LCM of 897,403,991,261 with Prime Factorization
| 3 | 897, 403, 991, 261 |
| 13 | 299, 403, 991, 87 |
| 23, 31, 991, 87 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 23 x 31 x 991 x 87 = 2397436119
Therefore, the lowest common multiple of 897,403,991,261 is 2397436119.
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.
897 x 403 x 991 x 261 = 93500008641
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.
897 : 1, 3, 13, 23, 39, 69, 299, 897
403 : 1, 13, 31, 403
991 : 1, 991
261 : 1, 3, 9, 29, 87, 261
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 897,403,991,261, is 1.
Now, the common factors can be found like this.
897:3x 13x 23
403:13x 31
991:991
261:3x 3x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13 = 39
Therefore, the value for common factors is 39.
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 = 93500008641/(1x39)
LCM = 93500008641/39
LCM = 2397436119
Thus, we can understand that the LCM of 897,403,991,261 is 2397436119.
