Question

Using all three methods, find the H. C. F of 20,25,35 and 50​

Answer 1

Answer:

Factors of 15 (Fifteen) = 1, 3, 5 and 15.

Factors of 35 (Thirty five) = 1, 5, 7 and 35.

Therefore, common factor of 15 (Fifteen) and 35 (Thirty five) = 1 and 5.

Highest common factor (H.C.F) of 15 (Fifteen) and 35 (Thirty five) = 5.
