Answer 1

Answer:

First, find all the factors of the given numbers individually. We see that the common factors of 18, 24 and 42 are 1, 2, 3 and 6. Since 6 is the highest of these common factors. Therefore, HCF of 18, 24 and 42 is 6.

Hope it helps

Have a great day

Answer 2

Answer:

HCF = HCF of Numerators/LCM of denominators. LCM = LCM of Numerators/ HCF of Denominators.

Step-by-step explanation:

First, find all the factors of the given numbers individually. We see that the common factors of 18, 24 and 42 are 1, 2, 3 and 6. Since 6 is the highest of these common factors. Therefore, HCF of 18, 24 and 42 is 6.
