Algebraic Manipulation

Question 1

What is a factor?

Answer 1

a number or algebraic expression that divides another number or expression evenly—i.e., with no remainder.
For example, 3 and 6 are factors of 12 because 12 ÷ 3 = 4 exactly and 12 ÷ 6 = 2 exactly

If a number divides the other number evenly, then the remainder is 0.

Question 2

HCF and LCM

Answer 2

The H.C.F. defines the greatest factor present in between given two or more numbers.
L.C.M. defines the least number which is exactly divisible by two or more numbers.
