Rajasthan Board RBSE Class 5 Maths Chapter 5 Multiples and Factors Ex 5.2

Find the factors of 18, 32, 28, 42, 45, 56 through division.

Question 1.
Find out the factors of given numbers.
(i) 7
(ii) 9
(iii) 16
(iv) 25
(v) 48
(vi) 63
Solution.
(i) Factors of 7 = 1, 7
(ii) Factors of 9= 1,3,9
(iii) Factors of 16 = 1, 2, 4, 8, 16
(iv) Factors of 25= 1, 5,25
(v) Factors of 48 = 1,2, 3, 4, 6, 8, 12, 16, 24, 48
(vi) Factors of 63 = 1, 3, 7, 9, 21, 63

Question 2.
Find out the factors of given numbers,
(i) 8 and 12
(ii) 10 and 20
(iii) 7 and 16
(iv) 18 and 32
Solution.
(i) 8 and 12
Factors of 8 = 1,2, 4, 8
Factors of 12 = 1,2, 3, 4, 6, 12
Therefore, common(RBSESolutions.com)factors of 8 and 12 = 1, 2, 4

(ii) 10 and 20
Factors of 10 = 1,2, 5, 10
Factors of 20 = 1, 2, 4, 5, 10, 20
Therefore, common factors of 10 and 20 = 1, 2, 5, 10

(iii) 7 and 16
Factors of 7 = 1 , 7
Factors of 16 = 1,2, 4, 8, 16
Therefore, common factors of 7 and 16 = 1

(iv) 18 and 32
Factors of 18 =1,2, 3, 6, 9, 18
Factors of 32 = 1,2, 4, 8, 16, 32
Therefore, common factors of 18 and 32 = 1, 2.

Question 3.
Find out the highest(RBSESolutions.com)common factors of 21 and 28.
Solution.

Therefore highest common factors of 21 and 28 = 7

Question 4.
Find out the highest number which can exactly divides 45 and 75.
Solution.
Factors of 45 = 1, 3, 5, 9, 15, 45.
Factors of 75 = 1, 3, 5, 15, 25, 75
Common factors of 45 and 75 = 1, 3, 5, 15
Highest common factor in factors = 15
Therefore 15 is the highest number which can exactly divides 45 and 75.

Question 5.
Find out the highest common common factors of 12,18 and 24.
Solution.
Factors of 12 = 1, 2, 3, 4, 6, 12
Factors of 18 = 1, 2, 3, 6, 9, 18
Factors of 24 = 1, 2, 3, 4, 6, 8, 12, 24
Common factors of 12, 18, 24 = 1, 2, 3, 6
Therefore highest(RBSESolutions.com)common factor of 12, 18 and 24 = 6

Question 6.
Find out the highest common factors of 15, 27 and 36.
Solution.
Factors of 15 = 1, 3, 5, 15
Factors of 27 = 1, 3, 9, 27
Facotors of 36 = 1, 2, 3, 4, 6, 12, 18, 36
Common factors of 15, 27 and 36 = 1,3
Therefore, highest common factor of 15, 27 and 36 = 3

Question 7.
Two milk containers filled with 20 litre and 30 litre of milk respectively. What will be the greatest(RBSESolutions.com)measurement of a container that can measure total milk of both container exactly ?
Solution.
Factors of 20 = 1, 2, 4, 5, 10, 20
Similarly factors of 30 = 1, 2, 3, 5, 6, 10, 15, 30
Highest common factor = 10
Therefore, greatest measurement of a container that can measure total milk of both container exactly is 10 litre.
