Given numbers are 1,979,717,121
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 1,979,717,121 is 7721373.
Find LCM of 1,979,717,121 with Prime Factorization
11 | 1, 979, 717, 121 |
1, 89, 717, 11 |
Multiply the prime numbers at the bottom and the left side.
11 x 1 x 89 x 717 x 11 = 7721373
Therefore, the lowest common multiple of 1,979,717,121 is 7721373.
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.
1 x 979 x 717 x 121 = 84935103
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.
1 : 1
979 : 1, 11, 89, 979
717 : 1, 3, 239, 717
121 : 1, 11, 121
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1,979,717,121, is 1.
Now, the common factors can be found like this.
1:
979:11x 89
717:3x 239
121:11x 11
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 = 84935103/(1x11)
LCM = 84935103/11
LCM = 7721373
Thus, we can understand that the LCM of 1,979,717,121 is 7721373.
