Given numbers are 927,399,991,189
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 927,399,991,189 is 366544143.
Find LCM of 927,399,991,189 with Prime Factorization
| 3 | 927, 399, 991, 189 |
| 3 | 309, 133, 991, 63 |
| 7 | 103, 133, 991, 21 |
| 103, 19, 991, 3 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 103 x 19 x 991 x 3 = 366544143
Therefore, the lowest common multiple of 927,399,991,189 is 366544143.
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.
927 x 399 x 991 x 189 = 69276843027
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.
927 : 1, 3, 9, 103, 309, 927
399 : 1, 3, 7, 19, 21, 57, 133, 399
991 : 1, 991
189 : 1, 3, 7, 9, 21, 27, 63, 189
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 927,399,991,189, is 1.
Now, the common factors can be found like this.
927:3x 3x 103
399:3x 7x 19
991:991
189:3x 3x 3x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 7 = 189
Therefore, the value for common factors is 189.
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 = 69276843027/(1x189)
LCM = 69276843027/189
LCM = 366544143
Thus, we can understand that the LCM of 927,399,991,189 is 366544143.
