Answer 2

Given,

The main numbers are 5 and 7

To find,

Listing first five odd multiples of 5 and 7 and finding their common multiples.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

To get the first five odd multiples of the given number, we have to multiply the given numbers with first five odd numbers (ie. 1,3,5,7,9).

First five odd multiples of 5 :

1×5 = 5 ; 3×5 = 15 ; 5×5 = 25 ; 7×5 = 35 ; 9×5 = 45

First five odd multiples of 7 :

1×7 = 7 ; 3×7 = 21 ; 5×7 = 35 ; 7×7 = 49 ; 9×7 = 63

Common multiple = 35

Hence, first five odd multiples of 5 are 5,15,25,35,45 and first five odd multiples of 7 are 7,21,35,49,63 And, their common multiple is 35
