Find The Largest Number To Divide All The Three Numbers Leaving The Remainders 4, 3, And 15 Respectively At The End?

Answer»

Here greatest number that can divide MEANS the HCF

Remainders are different so SIMPLY subtract remainders from NUMBERS

17 - 4 = 13; 42 - 3 = 39; 93 - 15 = 78

Now let's find HCF of 13, 39 and 78

By direct observation we can see that all numbers are divisible by 13.

? HCF = 13 = required greatest number.
