Find the LCM of 991, 205, 991, 347 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, 205, 991, 347. So, keep reading to learn more.
Given numbers are 991,205,991,347
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 991,205,991,347 is 70494785.
Find LCM of 991,205,991,347 with Prime Factorization
991 | 991, 205, 991, 347 |
1, 205, 1, 347 |
Multiply the prime numbers at the bottom and the left side.
991 x 1 x 205 x 1 x 347 = 70494785
Therefore, the lowest common multiple of 991,205,991,347 is 70494785.
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 205 x 991 x 347 = 69860331935
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
205 : 1, 5, 41, 205
991 : 1, 991
347 : 1, 347
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,205,991,347, is 1.
Now, the common factors can be found like this.
991:991
205:5x 41
991:991
347:347
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 = 69860331935/(1x991)
LCM = 69860331935/991
LCM = 70494785
Thus, we can understand that the LCM of 991,205,991,347 is 70494785.
