HCF of 2 and 5 by Long Division
- Step 1: Divide 5 by 2 and check the remainder.
- Step 2: Make the remainder 1 as the new divisor and the previous divisor 2 is the dividend and perform the long division again. The last divisor is our HCF.
- Step 3: Continue till you get the remainder as 0
You can find the HCF of 2 and 5 in any of the above methods but the solution will be the same.
