Question

The sum of the distinct primes that divide 5400 is

Answer 1

hey mate your answer is 10

Answer 2

Answer:

(2+3), (3+5), (5+7), (2+7), (3+7), (7+11)

Step-by-step explanation:

5400 = 2 X 3 X 3 X 3 X 2 X 2 X 5 X 5

If we look at the prime numbers from the minimum value,

it's

2, 3, 5, 7, 11, 13, 17, 19... and so on.

Now, the question demands the sum of any two 2 primes by which 5400 can be divided. Here are some examples;

i) 5400/(2+3) = 5400/5 = 1080

ii) 5400/(3+5) = 5400/8 = 675

iii) 5400/(5+7) = 5400/12 = 450

iv) 5400/(2+7) = 5400/9 = 600

v) 5400/(3+7) = 5400/10 = 540

vi) 5400/(7+11) = 5400/18 = 300
