Given numbers are 457,207,989
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 457,207,989 is 4067757.
Find LCM of 457,207,989 with Prime Factorization
23 | 457, 207, 989 |
457, 9, 43 |
Multiply the prime numbers at the bottom and the left side.
23 x 457 x 9 x 43 = 4067757
Therefore, the lowest common multiple of 457,207,989 is 4067757.
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.
457 x 207 x 989 = 93558411
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.
457 : 1, 457
207 : 1, 3, 9, 23, 69, 207
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 457,207,989, is 1.
Now, the common factors can be found like this.
457:457
207:3x 3x 23
989:23x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
23 = 23
Therefore, the value for common factors is 23.
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 = 93558411/(1x23)
LCM = 93558411/23
LCM = 4067757
Thus, we can understand that the LCM of 457,207,989 is 4067757.
