Question

find the largest number that will we divide 398,436and 542 leaving the remainder 7,11and 15 respectively​

Answer 1

Answer:

Deducting the remainders from numbers we get,

398−7=391

436−11=425

542−15=527

H.C.F of these new numbers is the largest possible number that divides 398,436,542 leaving respective remainders

391=17×23

425=17×5

2

527=17×31

∴ Answer = H.C.F(391,425,527)=17

I hope so this answer is helpful for you.
