Question

what is the sum of the numbers that are multiples of 7 as well as the factors of 42​

Answer 1

Answer:

5

Step-by-step explanation:

let the no.s be 7x, 7y

7×6=42

so x,y can be 2 and 3, as 7×2=14 is a factor of 42, 7×3=21 is also a factor of 42

so no.s are 2,3

sum is 5

actually x,y can be 1,2 or 2,3 or 1,3

so sum can be 5 or 4 or 3
