What is the greatest common divisor of 18 and 30______ The least common multiple is______ ．

What is the greatest common divisor of 18 and 30______ The least common multiple is______ ．

30 = 2 × 3 × 518 = 2 × 3 × 3, so the greatest common divisor of 30 and 18 is 2 × 3 = 6, and the least common multiple is 2 × 3 × 5 × 3 = 90

15 and 18 and 32, 5 and 8 and 10 least common multiple and greatest common divisor by short division, what is it?

15=3*5
18=2*3*3
32＝2*2*2*2*2
Least common multiple: 2 * 2 * 2 * 2 * 3 * 3 * 5 = 1440
Greatest common divisor: 1
5=5
8=2*2*2
10=2*5
Least common multiple: 2 * 2 * 2 * 5 = 40
Greatest common divisor: 1

24 and 30, 20 and 45, 35 and 49, 5, 25 and 75, 16, 18 and 32
There is a cuboid glass fish tank, measuring 0.75 meters long, 0.55 meters wide and 0.3 meters high from inside. It is full of water. Now pour all the water into a square glass tank, measuring 0.5 meters long from inside. How high is the water surface in the square fish tank?

24 and 30 greatest common divisor 6 least common multiple 4 * 5 * 6 = 120 20 and 45 greatest common divisor 5 least common multiple 4 * 5 * 9 = 18035 and 49 greatest common divisor 7 least common multiple 5 * 7 * 7 = 2455, 25 and 75 greatest common divisor 5 least common multiple 7516, 18 and 32 greatest common divisor 2 least common multiple 2 * 9 * 16 = 2880.75 * 0.5

The greatest common divisor of two numbers is 3 and the least common multiple is 45. What are these two numbers?
The greatest common divisor of the two numbers is 3, and the least common multiple is 45. These two numbers are? And?

3 and 45

The greatest common divisor of two numbers is 3 and the least common multiple is 45. What are these two numbers
Formula

One is 15, one is 3
Suppose one number is 3x and one number is 3Y
Then 3x * n = 3Y * m = 45
X*N=Y*M=15
15 can only be disassembled into 5 and 3
So the optional numbers 3, 5, 15,
Only 3 and 15 meet the requirements

It is known that the greatest common divisor of two numbers is 6 and the least common multiple is 72

6 and 72
There should be a lot more

It is known that the sum of two numbers is 40, and the sum of their greatest common divisor and least common multiple is 56
ample reward
People can understand)

The greatest common factor of two numbers = the sum of two numbers and the greatest common factor of the least common multiple of two numbers (you can prove it with examples) the greatest common factor of 40 and 56 is 8. Let a and b40 = 8 (a + b) be the unique prime factors of these two numbers, a + B = 556 = 8 + 8 × a × B = 8 × (1 + a × b) be 1 + a × B = 7, and a × B = 65 = 1 + 4 = 2 +

Given that the greatest common divisor of two numbers is 13 and the least common multiple is 78, find the difference between the two numbers

78 is a multiple of 13, so the smallest one is 13 and the largest one is 78-13 = 65

The least common multiple of 24 and 18.36

72

How to find the least common multiple of 18, 24 and 36

18=2*3*3
24=2*2*2*3
36=2*2*3*3
Least common multiple = 2 * 2 * 2 * 3 * 3 = 72
