HOW TO USE
Tap NUMBER A or NUMBER B to edit
Type digits or use keypad
Press ENTER to compute
EXAMPLE
A=12, B=18
HCF = 6
LCM = (12×18)/6 = 36
HCF
Largest number that divides both
Uses Euclid’s algorithm (remainders)
LCM
Smallest common multiple of both
LCM = (A×B)/HCF
KEYS
NEXT/TAB next field
BS deletes • CLR clears
C all • SWAP swaps
I help • P back
TIP
If A=B, then HCF=A and LCM=A
If one is 0, HCF/LCM are not shown

HOW TO USE
Tap A or B → enter digits
Press ENTER to compute
EXAMPLE
12 and 18 → HCF 6
LCM = (12×18)/6 = 36
KEYS
NEXT/TAB next field
BS deletes • CLR clears
C all • SWAP swaps
TIP
If either input is 0, results aren’t shown
HCF is used to simplify ratios/fractions
