Question

find the greatest number that will divide 217,310 and 713 without leaving any remainder​

Answer 1

Answer:

31

Step-by-step explanation:

All you have to do is use HCF

You could do this by prime factorisation.......(1)

After doing that take all the common prime factors for each of the numbers

In this case 217= 31*7

310=31*5*2

713= 31*23

Hence 31 the common number is the HIGHEST COMMON FACTOR

It will decide all your numbers without leaving a remainder
