Given numbers are 663,189,913
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 663,189,913 is 38135097.
Find LCM of 663,189,913 with Prime Factorization
| 3 | 663, 189, 913 |
| 221, 63, 913 |
Multiply the prime numbers at the bottom and the left side.
3 x 221 x 63 x 913 = 38135097
Therefore, the lowest common multiple of 663,189,913 is 38135097.
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.
663 x 189 x 913 = 114405291
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.
663 : 1, 3, 13, 17, 39, 51, 221, 663
189 : 1, 3, 7, 9, 21, 27, 63, 189
913 : 1, 11, 83, 913
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 663,189,913, is 1.
Now, the common factors can be found like this.
663:3x 13x 17
189:3x 3x 3x 7
913:11x 83
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 = 114405291/(1x3)
LCM = 114405291/3
LCM = 38135097
Thus, we can understand that the LCM of 663,189,913 is 38135097.
