Given numbers are 991,707,905,469
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 991,707,905,469 is 42483124495.
Find LCM of 991,707,905,469 with Prime Factorization
| 7 | 991, 707, 905, 469 |
| 991, 101, 905, 67 |
Multiply the prime numbers at the bottom and the left side.
7 x 991 x 101 x 905 x 67 = 42483124495
Therefore, the lowest common multiple of 991,707,905,469 is 42483124495.
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 707 x 905 x 469 = 297381871465
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
707 : 1, 7, 101, 707
905 : 1, 5, 181, 905
469 : 1, 7, 67, 469
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,707,905,469, is 1.
Now, the common factors can be found like this.
991:991
707:7x 101
905:5x 181
469:7x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7 = 7
Therefore, the value for common factors is 7.
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 = 297381871465/(1x7)
LCM = 297381871465/7
LCM = 42483124495
Thus, we can understand that the LCM of 991,707,905,469 is 42483124495.
