Given numbers are 991,991,663,965
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 991,991,663,965 is 634036845.
Find LCM of 991,991,663,965 with Prime Factorization
991 | 991, 991, 663, 965 |
1, 1, 663, 965 |
Multiply the prime numbers at the bottom and the left side.
991 x 1 x 1 x 663 x 965 = 634036845
Therefore, the lowest common multiple of 991,991,663,965 is 634036845.
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.
991 x 991 x 663 x 965 = 628330513395
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.
991 : 1, 991
991 : 1, 991
663 : 1, 3, 13, 17, 39, 51, 221, 663
965 : 1, 5, 193, 965
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,991,663,965, is 1.
Now, the common factors can be found like this.
991:991
991:991
663:3x 13x 17
965:5x 193
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
991 = 991
Therefore, the value for common factors is 991.
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 = 628330513395/(1x991)
LCM = 628330513395/991
LCM = 634036845
Thus, we can understand that the LCM of 991,991,663,965 is 634036845.
