Given numbers are 832, 988, 644, 438

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

Apply this formula for all numbers.

Step1:

LCM(832, 988) = 15808

GCD(832, 988) = ( 832 x 988 ) / 15808

= 832 / 988

= 832

Step2:

LCM(52, 644) = 8372

GCD(52, 644) = ( 52 x 644 ) / 8372

= 52 / 644

= 52

Step3:

LCM(4, 438) = 876

GCD(4, 438) = ( 4 x 438 ) / 876

= 4 / 438

= 4

So, Greatest Common Divisor of 832, 988, 644, 438 is 2
