Among the following correct statement is a) The number of ways of expressing 36 as a product of two facrors is 4

b) The sum of odd divisors of 18 is 13 c) 220 and 274 are amicable numbers

d) G. C.D of 100, 25 is 1

Step-by-step explanation:

a) False. There are three factor pairs for 36:

1×36

2×18

3×12

4×9

6×6

b) True.

18 = 2×3²

Odd divisors of 18: 1, 3, 9

1+3+9 = 13

c) False

100 = 2×5²

25 = 5²

Greatest common divisor = 25
