Question

21) Activity We discovered the relationship between the HCF and LCM of two natural numbers, ‘HCF x LCM = Product of the two numbers’. Check whether the relation is applicable for more than two natural numbers using 5 different examples.

Answer 1

Answer:

No it is applicable for more than two natural numbers

Step-by-step explanation:

We will learn the relationship between H.C.F. and L.C.M. of two numbers.

First we need to find the highest common factor (H.C.F.) of 15 and 18 which is 3.

Then we need to find the lowest common multiple (L.C.M.) of 15 and 18 which is 90.

H.C.F. × L.C.M. = 3 × 90 = 270

Also the product of numbers = 15 × 18 = 270

Therefore, product of H.C.F. and L.C.M. of 15 and 18 = product of 15 and 18.

Answer 2

Step-by-step explanation:

it is correct.

when, HCF×LCM=products of the two numbers.
