(b) 124
(c) 100
(d) 275
(e) 240​

Answer 1

Answer:

108= 2*2*3*3*3

124= 2*2*31

100= 2*2*5*5

275= 5*5*11

240= 2*2*2*2*3*5

Step-by-step explanation:

first 108 is divided by prime number i.e 2 ...54

then 54 is agian divided by smallest prime number that divides 54 i.e 2 ....27

then 27 is again divided by smallest prime number that can divided 27 i.e 3...9

then 9 is divided by smallest prime number that can divide it i.e 3 ....3

again 3 is divided by 3....1

stop these steps when quotient come 1 ....

hence multiplication of all the quotient gives us the number i.e. 108

Answer 2

108 = 2*2*3*3*3

124 = 2*2*31

100 = 2*2*5*5

275 = 5*5*11

240 = 2*2*2*2*3*5
