Given numbers are 115,991,121,836
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 115,991,121,836 is 1048022140.
Find LCM of 115,991,121,836 with Prime Factorization
11 | 115, 991, 121, 836 |
115, 991, 11, 76 |
Multiply the prime numbers at the bottom and the left side.
11 x 115 x 991 x 11 x 76 = 1048022140
Therefore, the lowest common multiple of 115,991,121,836 is 1048022140.
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.
115 x 991 x 121 x 836 = 11528243540
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.
115 : 1, 5, 23, 115
991 : 1, 991
121 : 1, 11, 121
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 115,991,121,836, is 1.
Now, the common factors can be found like this.
115:5x 23
991:991
121:11x 11
836:2x 2x 11x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 11528243540/(1x11)
LCM = 11528243540/11
LCM = 1048022140
Thus, we can understand that the LCM of 115,991,121,836 is 1048022140.
