Question

If the LCM of 56 and 70 is 280 find their HCF

Answer 1

Answer:

HCF = 14

Step-by-step explanation:

As we know that ;

LCM * HCF = Product of numbers

Therefore;

280 * HCF =  56 * 70

HCF =  $\frac{56 * 70}{280}$

HCF = 14

Answer 2

Answer:

5

Step-by-step explanation:

Product of two numbers

HCF* LCM

so, HCF = product of two numbers/LCM

=280/56

=5

Therefore , the required HCF IS 5
