Question

Find the largest numbers which exactly divides 418 and 1866 leaving remainders 4 and 3 respectively

Answer 1

Answer:

207

Step-by-step explanation:

the number which exactly divides 418=

4=418÷104.5

So,418÷104.5=4

The number which exactly divides 1866=

3=1866÷3=622

So,1866÷622=3

Answer 2

Answer:

To find the largest number which exactly divides 280 and 1245 leaving remainders 4 and 3 respectively, we subtract 4 and 3 from 280 and 1245.

280−4=276

1245−3=1242

276=2×2×3×23

1242=2×3×3×3×23

HCF=2×3×23=138

Therefore, the largest number which exactly divides 280 and 1245 leaving remainders 4 and 3 respectively is 138.
