Find the LCM of 991, 991, 631 with the LCM of Two or More Numbers Calculator. Here we are teaching you two different methods through which you can calculate the LCM of 991, 991, 631. So, keep reading to learn more.
Given numbers are 991,991,631
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 991,991,631 is 625321.
Find LCM of 991,991,631 with Prime Factorization
991 | 991, 991, 631 |
1, 1, 631 |
Multiply the prime numbers at the bottom and the left side.
991 x 1 x 1 x 631 = 625321
Therefore, the lowest common multiple of 991,991,631 is 625321.
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 631 = 619693111
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
631 : 1, 631
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,991,631, is 1.
Now, the common factors can be found like this.
991:991
991:991
631:631
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 = 619693111/(1x991)
LCM = 619693111/991
LCM = 625321
Thus, we can understand that the LCM of 991,991,631 is 625321.
