Given numbers are 441, 819, 770, 384

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

Apply this formula for all numbers.

Step1:

LCM(441, 819) = 5733

GCD(441, 819) = ( 441 x 819 ) / 5733

= 441 / 819

= 441

Step2:

LCM(63, 770) = 6930

GCD(63, 770) = ( 63 x 770 ) / 6930

= 63 / 770

= 63

Step3:

LCM(7, 384) = 2688

GCD(7, 384) = ( 7 x 384 ) / 2688

= 7 / 384

= 7

So, Greatest Common Divisor of 441, 819, 770, 384 is 1
