list the common factors for each pair of numbers. Then find the greatest common factor for each pair.

18 and 30, 9 and 25
60 and 45, 23 and 29
49 and 14, 140 and 25
142 and 148, 84 and 105

actually i forgot one number the number is actually 6

find each multiplication problem that goes into each number starting with 2 and go up. do that with the other number you are comparing and then compare.

example

36 and 12

36 = 1,2,3,4,6,9,12,18,36 are factors 36
1x36
2x18
3x12
4x9
6

12 = 1,2,3,4,6,12 are factors of 12
1x12
2x6
3x4

now you compare both numbers of their factors
12 = 1,2,3,4,6,12
36 = 1,2,3,4,6,9,12,18,36
find the numbers they have in common which are 1,2,3,4,. then look at which number is greater

the number is 4

it good and fun

Alright, let's find the common factors and the greatest common factors for each pair!

For 18 and 30:

For 9 and 25:
The common factors of 9 and 25 are 1.
The greatest common factor of 9 and 25 is 1. (Can't get any greater than that!)

For 60 and 45:
The common factors of 60 and 45 are 1, 3, 5, 15.
The greatest common factor of 60 and 45 is 15.

For 23 and 29:
The common factors of 23 and 29 are 1.
The greatest common factor of 23 and 29 is 1. (Again, can't get any greater than that!)

For 49 and 14:
The common factors of 49 and 14 are 1 and 7.
The greatest common factor of 49 and 14 is 7.

For 140 and 25:
The common factors of 140 and 25 are 1 and 5.
The greatest common factor of 140 and 25 is 5.

For 142 and 148:
The common factors of 142 and 148 are 1 and 2.
The greatest common factor of 142 and 148 is 2.

For 84 and 105:
The common factors of 84 and 105 are 1, 3, 7.
The greatest common factor of 84 and 105 is 7.

Hope that brought a smile to your face!

To find the common factors and the greatest common factor (GCF) for each pair of numbers, we can follow these steps:

1. List the factors for each number in the pair.
2. Identify the common factors of both numbers.
3. Determine the greatest common factor from the common factors.

Let's go through each pair of numbers one by one:

Pair 1: 18 and 30
Factors of 18: 1, 2, 3, 6, 9, 18
Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30
Common factors: 1, 2, 3, 6
Greatest common factor: 6

Pair 2: 9 and 25
Factors of 9: 1, 3, 9
Factors of 25: 1, 5, 25
Common factors: 1
Greatest common factor: 1

Pair 3: 60 and 45
Factors of 60: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
Factors of 45: 1, 3, 5, 9, 15, 45
Common factors: 1, 3, 5, 15
Greatest common factor: 15

Pair 4: 23 and 29
Factors of 23: 1, 23
Factors of 29: 1, 29
Common factors: 1
Greatest common factor: 1

Pair 5: 49 and 14
Factors of 49: 1, 7, 49
Factors of 14: 1, 2, 7, 14
Common factors: 1, 7
Greatest common factor: 7

Pair 6: 140 and 25
Factors of 140: 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
Factors of 25: 1, 5, 25
Common factors: 1, 5
Greatest common factor: 5

Pair 7: 142 and 148
Factors of 142: 1, 2, 71, 142
Factors of 148: 1, 2, 4, 37, 74, 148
Common factors: 1, 2
Greatest common factor: 2

Pair 8: 84 and 105
Factors of 84: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84
Factors of 105: 1, 3, 5, 7, 15, 21, 35, 105
Common factors: 1, 3, 7, 21
Greatest common factor: 21

So, the greatest common factors for each pair are:
Pair 1: 6
Pair 2: 1
Pair 3: 15
Pair 4: 1
Pair 5: 7
Pair 6: 5
Pair 7: 2
Pair 8: 21
