GCF

100

Find the GCF of 18 and 40

2

200

Find the GCF of 8 and 13.

The GCF is 1.

1 is also called a coprime.

300

Find the GCF of 32 and 52

4

LCM

100

Find the LCM of 2 and 5

10

200

Find the LCM of 4 and 6

Prime Factorization & Factor Pairs

100

Give one factor pair for 30.

Any of these:

1 x 30

2 x 15

3 x 10

5 x 6

200

Find the Prime Factorization of 49

7 x 7

300

Find the Prime Factorization of 75

 3 x 5 x 5 

Place Value & Division

100

True or False.

In the number 2200, the two in the thousands place is 10 times larger than the two in the hundreds place.

True.

200

Jake divides 75 in equal groups of 6.
How much is left over?

75 / 6=12 R3

It goes in 12 times and has 3 left over.

6 x 12 = 72
72+3 =75

divisor x quotient + remainder = dividend

300

96 / 7 = 13 R 5

How much would the dividend (96) need to be increased by so that isn't any left over?

It would need to be increased by 2.

98/7= 14

There were 5 left over. If we increased the dividend by 2, then 7 could have been divided into 98 one more time, without a remainder.

Distributive Property

100

Is this expression rewritten using the distributive property.  True or False

4(25)

(4 + 20) x (4 + 5)

False.

Should be (4 x 20) + (4 x 5)

200

Rewrite this expression using the distributive property.

8(42)

8 x 40 + 8 x 2

300

Rewrite this problem using the distributive property.

(hint: there is more than 1 way)

16 + 20

4 (4 + 5)

2 (8 + 10)

400

Rewrite this addition expression using the GCF and the distributive property.

25 + 15

The GCF is 5.

5(5 + 3)
