Given numbers are 18,99,45,437
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 18,99,45,437 is 432630.
Find LCM of 18,99,45,437 with Prime Factorization
3 | 18, 99, 45, 437 |
3 | 6, 33, 15, 437 |
2, 11, 5, 437 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 2 x 11 x 5 x 437 = 432630
Therefore, the lowest common multiple of 18,99,45,437 is 432630.
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.
18 x 99 x 45 x 437 = 35043030
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.
18 : 1, 2, 3, 6, 9, 18
99 : 1, 3, 9, 11, 33, 99
45 : 1, 3, 5, 9, 15, 45
437 : 1, 19, 23, 437
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 18,99,45,437, is 1.
Now, the common factors can be found like this.
18:2x 3x 3
99:3x 3x 11
45:3x 3x 5
437:19x 23
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 3 = 81
Therefore, the value for common factors is 81.
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 = 35043030/(1x81)
LCM = 35043030/81
LCM = 432630
Thus, we can understand that the LCM of 18,99,45,437 is 432630.
