Given numbers are 991,546,601,427
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 991,546,601,427 is 19836753846.
Find LCM of 991,546,601,427 with Prime Factorization
| 7 | 991, 546, 601, 427 |
| 991, 78, 601, 61 |
Multiply the prime numbers at the bottom and the left side.
7 x 991 x 78 x 601 x 61 = 19836753846
Therefore, the lowest common multiple of 991,546,601,427 is 19836753846.
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 546 x 601 x 427 = 138857276922
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
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
601 : 1, 601
427 : 1, 7, 61, 427
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,546,601,427, is 1.
Now, the common factors can be found like this.
991:991
546:2x 3x 7x 13
601:601
427:7x 61
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 = 138857276922/(1x7)
LCM = 138857276922/7
LCM = 19836753846
Thus, we can understand that the LCM of 991,546,601,427 is 19836753846.
