Given numbers are 981,779,247,779
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 981,779,247,779 is 9934587.
Find LCM of 981,779,247,779 with Prime Factorization
19 | 981, 779, 247, 779 |
41 | 981, 41, 13, 41 |
981, 1, 13, 1 |
Multiply the prime numbers at the bottom and the left side.
19 x 41 x 981 x 1 x 13 x 1 = 9934587
Therefore, the lowest common multiple of 981,779,247,779 is 9934587.
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.
981 x 779 x 247 x 779 = 147041822187
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.
981 : 1, 3, 9, 109, 327, 981
779 : 1, 19, 41, 779
247 : 1, 13, 19, 247
779 : 1, 19, 41, 779
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,779,247,779, is 1.
Now, the common factors can be found like this.
981:3x 3x 109
779:19x 41
247:13x 19
779:19x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19x 19x 41 = 14801
Therefore, the value for common factors is 14801.
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 = 147041822187/(1x14801)
LCM = 147041822187/14801
LCM = 9934587
Thus, we can understand that the LCM of 981,779,247,779 is 9934587.
