It can be: (5*6)-21 = 28
2 x 14 = 28
Using 1, 2, and 3, you can make 27 whole numbers.
2 * 2 * 2 * 2 It's not possible to make 16 without using the same numbers twice or without using whole numbers.
2 x 2 x 7
It can be: (5*6)-21 = 28
2 x 14 = 28
(4 x 5) + (2 x 4) = 28

1 and 28. 2 and 14. 4 and 7.
2 x 2 x 7
28 is not a prime number because it is divisible by 2, 4, 7, and 14. Prime numbers are only divisible by 1 and themselves without any other factors.
A lot of 4 numbers make 28. You could have 4x7, or 2x6 + 2x8 or even 1+2+3+22 etc. The permuntations are vast.

This is the way to do it.. Factorize 4,28 using prime numbers only (Prime factorization) till you get 1,1. The prime numbers used are 2,2 & 7 Therefore HCF(4,28)= 2*2*7 = 28.
