Given numbers are 305, 421, 384, 942
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(305, 421) = 128405
GCD(305, 421) = ( 305 x 421 ) / 128405
= 305 / 421
= 305
Step2:
LCM(1, 384) = 384
GCD(1, 384) = ( 1 x 384 ) / 384
= 1 / 384
= 1
Step3:
LCM(1, 942) = 942
GCD(1, 942) = ( 1 x 942 ) / 942
= 1 / 942
= 1
So, Greatest Common Divisor of 305, 421, 384, 942 is 1
