Question

Find the difference between the LCM and the HCF of the numbers 31 and 61

Answer 1

Answer:

1890

Step-by-step explanation:

HCF

Hence both the numbers are prime so both are only devisible by either by 1 or by themselves so HCF would be 1.(HCF of two prime numbers is always 1)

LCM

Always remember that the LCM of two prime numbers is always their product. There doesn't exist any comman multiple which is less than their product.

Hence LCM of 31 and 61 would be 1891

And thus difference would be 1891-1=1890

So the answer is 1890
