Given numbers are 256, 384, 874, 405
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(256, 384) = 768
GCD(256, 384) = ( 256 x 384 ) / 768
= 256 / 384
= 256
Step2:
LCM(128, 874) = 55936
GCD(128, 874) = ( 128 x 874 ) / 55936
= 128 / 874
= 128
Step3:
LCM(2, 405) = 810
GCD(2, 405) = ( 2 x 405 ) / 810
= 2 / 405
= 2
So, Greatest Common Divisor of 256, 384, 874, 405 is 1
