The prime numbers 5 and 3 are both factors that are common to 30 and 75. The product of these factors is 3×5 = 15. Thus, the “Greatest Common Factor” of 30 and 75 is 15. To check this result, divide 15 into 30 and then into 75, and verify that in each case the result is a whole number.

= 2 x 2 x 7 are the prime factors of 28. = 2 x 2 x 7 are the prime factors of 28. Two (2) and seven (7) are prime numbers because each satisfies the definition of a prime number. A prime number is a positive integer that is exactly divisible (a zero remainder) by exactly TWO positive integers: itself and 1.
