What is the best way to store large numbers in 8-bit registers in AVR in assembler?

For example, there is a formula for determining the thermistor resistance:
A*(B/C-1) = D
1000*(1023/430-1)= 1300R
Here A is a balancing resistor, B is the ADC capacity, C is the ADC value, and D is the thermistor resistance.
How can such large numbers be organized in assembler memory and then compared to the resistance of the thermistor against another large number?
