Question

Write two pairs of numbers such that the lcm of each pair of numbers is the product of the pair of number​s

Answer 1

1st pair of numbers:

7 and 3

Step-by-step explanation:

7 × 3 = 21

Multiples of 7: 7, 14, 21 ,28 and so on...

Multiples of 3: 3, 6, 9, 12, 15, 18, 21 ,24 , 27 ,30 and so on....

Here if you will notice carefully at both 7 and 3's multiples,you will see the number '21' in both the numbers' multiples.Also if we multiply 7 and 3,you will get 21.So 7 and 3 can be one of the pair of numbers that the LCM of the pair of numbers is the product of the pair of numbers.

2nd pair of numbers:

4 and 5

Step-by-step explanation:

Another such pair of numbers is 4 and 5.

4 × 5 = 20

Multiples of 4: 4, 8, 12, 16, 20, 24, 28 and so on......

Multiples of 5: 5, 10, 15, 20, 25, 30 and so on.......

Here also if you will notice carefully at both 4 and 5's multiples,you will see the number '20' in both the numbers' multiples.Also if we multiply 4 and 5,you will get 20.

There are many such pairs of numbers apart from these two, but I just gave you two of the examples of those pairs of numbers.
