Answer:
The greatest length of a measuring tape = 20 cm
GIVEN:
Length = 440 cm and 820 cm
TO FIND:
The greatest length of a measuring tape.
SOLUTION:
Firstly we have to find the HCF of 440 cm and 820 cm
Prime factorisation:
=> 440 = 2*2*2*5*11
440 = 2*2*2*5*11=> 820 = 2*2*5*41
HCF = 2*2*5
= 20
The greatest length of a measuring tape = 20 cm
