Given numbers are 18,26,90,675
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 18,26,90,675 is 17550.
Find LCM of 18,26,90,675 with Prime Factorization
2 | 18, 26, 90, 675 |
3 | 9, 13, 45, 675 |
3 | 3, 13, 15, 225 |
5 | 1, 13, 5, 75 |
1, 13, 1, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 1 x 13 x 1 x 15 = 17550
Therefore, the lowest common multiple of 18,26,90,675 is 17550.
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 26 x 90 x 675 = 28431000
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
26 : 1, 2, 13, 26
90 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90
675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 18,26,90,675, is 1.
Now, the common factors can be found like this.
18:2x 3x 3
26:2x 13
90:2x 3x 3x 5
675:3x 3x 3x 5x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3x 3x 3x 5 = 1620
Therefore, the value for common factors is 1620.
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 = 28431000/(1x1620)
LCM = 28431000/1620
LCM = 17550
Thus, we can understand that the LCM of 18,26,90,675 is 17550.
