Given numbers are 432, 808, 990, 969

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

Apply this formula for all numbers.

Step1:

LCM(432, 808) = 43632

GCD(432, 808) = ( 432 x 808 ) / 43632

= 432 / 808

= 432

Step2:

LCM(8, 990) = 3960

GCD(8, 990) = ( 8 x 990 ) / 3960

= 8 / 990

= 8

Step3:

LCM(2, 969) = 1938

GCD(2, 969) = ( 2 x 969 ) / 1938

= 2 / 969

= 2

So, Greatest Common Divisor of 432, 808, 990, 969 is 1
