Step-by-step explanation:
Solution :-
1.
i) Given numbers are 3 and 4
The first 3 multiples of 3
= 3×1 , 3×2 , 3×3
= 3,6,9
The first 3 multiples of 4
= 4×1 , 4×2 , 4×3
= 4,8,12
ii) Given numbers are 5 and 10
The first 3 multiples of 5
= 5×1 , 5×2 , 5×3
= 5,10,15
The first 3 multiples of 10
= 10×1 , 10×2 , 10×3
=10,20,30
iii) Given numbers are 8 and 12
The first 3 multiples of 8
= 8×1 , 8×2 , 8×3
= 8,16,24
The first 3 multiples of 12
= 12×1 , 12×2 , 12×3
= 12,24,36
2)
i) Given number = 36
36 = 1×36
36 = 2×18
36 = 3×12
36 = 4×9
36 = 6×6
36 = 9×4
36 = 12×3
36 = 18×2
36 = 36×1
The factors of 36 = 1,2,3,4,6,9,12,18,36
ii) Given number = 75
75 = 1×75
75 = 3×25
75 = 5×15
75 = 15×5
75 = 25×3
75 = 75×1
The factors of 75 = 1,3,5,15,25,75
Used formulae:-
→ Multiples of a number obtained by multiplying the given number with 1,2,3...
→ Every number has infinite number of multiples.
→ A number divides the given number exactly then the number is called its factor .
→ 1 is a factor of every number.
