What is an expression?
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
The greatest common factor is the largest positive number which can be divided into given numbers evenly.
The expression will be simplified as below:-
E = 24a + 72b - 40c
Take the number 8 common from the expression.
E = 8 ( 3a + 9b -5c ).
Therefore, the equation in a simple form by using the greatest common factor is 8 ( 3a + 9b -5c ).
