GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(644, 880) = 141680

GCD(644, 880) = ( 644 x 880 ) / 141680

= 644 / 880

= 644

Step2:

LCM(4, 992) = 992

GCD(4, 992) = ( 4 x 992 ) / 992

= 4 / 992

= 4

Step3:

LCM(4, 440) = 440

GCD(4, 440) = ( 4 x 440 ) / 440

= 4 / 440

= 4

So, Greatest Common Divisor of 644, 880, 992, 440 is 4
