Question

103: Find the greatest number which divides 42 and 56 exactly.​

Answer 1

Answer:

Here, the required number is 14.

Step-by-step explanation:

Here, As given in question, we have to find out the greatest number, so we would find out the HCF of the given numbers

=42=2×3×7

=56=2×2×2×7

Now, As we know that HCF of numbers is the multiplication of numbers occuring in every given number's factors.

So, HCF=2×7=14

Hence, 14 is the number which divides 42 and 56 exactly.

Thank you.
