Step-by-step explanation:

to find the largest number(hcf),

let us minus 398 with 7=(398-7)=391

let us minus 436 with 11=(436-11)=425

again let us minus 542 with 15=(542-15)=527

now,let us take out the LCm of 391,425and527

we get, 391=17 and 23

425=5,5 and 17

527=17 and 31

since the number 17 is repeating in all the LCm numbers,therefore 17 is the largest number that will divide 398,436 and 542 leaving remainder 7,11 and 15.

hope it helps, and please follow me, thanks
