Given numbers are 991,309,979,699
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 991,309,979,699 is 69850697433.
Find LCM of 991,309,979,699 with Prime Factorization
| 3 | 991, 309, 979, 699 |
| 991, 103, 979, 233 |
Multiply the prime numbers at the bottom and the left side.
3 x 991 x 103 x 979 x 233 = 69850697433
Therefore, the lowest common multiple of 991,309,979,699 is 69850697433.
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 309 x 979 x 699 = 209552092299
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
309 : 1, 3, 103, 309
979 : 1, 11, 89, 979
699 : 1, 3, 233, 699
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,309,979,699, is 1.
Now, the common factors can be found like this.
991:991
309:3x 103
979:11x 89
699:3x 233
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 209552092299/(1x3)
LCM = 209552092299/3
LCM = 69850697433
Thus, we can understand that the LCM of 991,309,979,699 is 69850697433.
