Question

5. Find the HCF of the numbers using long division method.
a. 63. 105
b. 252, 490
c. 216, 900
d. 2346, 4761
e. 261, 638, 812
f. 1173, 1275, 1581​

Answer 1

Answer:

Step 1: Divide the largest number by the smallest number. Step 2: Take divisor as new dividend and remainder as the new divisor, i.e. divide the first divisor by the first remainder. Step 3: Proceed till the remainder is zero and the last divisor will be the HCF of the given numbers. Therefore, HCF of 24 and 15 is 3.
