LCM Program

START INP $//$ Input the first number

STA NUM$\_$A $//$ Store first number in address NUM$\_$A

INP $//$ Input the second number

STA NUM$\_$B $//$ Store second number in address NUM$\_$B

CheckFirstNum

LDA NUM$\_$A $//$ Load the first number

BRP SECONDNUM $//$ Branch to SECONDNUM, if first number is positive

LDA NEGATIVEONE $//$ Load $-1$

OUT $//$ Output $-1$

BRA CHECK$\_$NEGATIVE $//$ Branch to CHECKNEGATIVE to continue

CheckSecondNum

LDA NUM$\_$B $//$ Load the second number

BRP CHECK$\_$DIVISION $//$ Branch to CHECK$\_$DIVISION, if second num is positive

LDA NEGATIVEONE $//$ Load $-1$

OUT $//$ Output $-1$

BRA CHECK$\_$NEGATIVE $//$ Branch to CHECKNEGATIVE to continue

CheckNegative

LDA NUM$\_$A $//$ Load the first number into ACC

BRP CHECKSEC$\_$NEG $//$ Branch to CHECKSEC$\_$NEG, if first num is positive

LDA NUM$\_$A $//$ load the first number again into ACC

STA LOCATION$\_$A $//$ Store it in LOCATION$\_$A

CheckSecondNegative

LDA NUM$\_$B $//$ Load the second number into ACC

BRP CHECK$\_$DIVISION $//$ Branch to CHECK$\_$DIVISION, if sec number is positive

LDA NUM$\_$B $//$ Load the second number again into ACC

STA LOCATION$\_$B $//$ Store it in LOCATION$\_$B

BRA CHECKDIVISION $//$ Branch to CHECKDIVISION

CheckDIvision

LDA NUM$\_$A $//$ Load the first number into ACC

DIV NUM$\_$B $//$ Divide ACC by the second number

STA QUOTIENT $//$ Store the Quotient

LDA QUOTIENT $//$ Load the Quotient

MUL NUM$\_$B $//$ Multiply the quotient by the second number

SUB NUM$\_$A $//$ Subtract the first number

BRZ OUTPUTRESULT $//$ If the result is $0$ then branch to OUTPUTRESULT

LDA ZERO $//$ Load $0$ in ACC

OUT $//$ Output $0$ as result

BRA START $//$ Branch to the start to input new values

Output results

LDA QUOTIENT $//$ Load the quotient

OUT $//$ Output quotient

END HLT $//$ HALT the program

NUM$\_$A DAT $//$ Memory space for the first number

NUM$\_$B DAT $//$ Memory space for the second number

QUOTIENT DAT $//$ Memory space to store quotient

LOCATION$\_$A DAT $//$ Temporary storage for first number

LOCATION$\_$B DAT $//$ Temporary storage for second number

NEGATIVEONE DAT $-1//$ Store $-1$

ZERO DAT $0//$ Store $0$
