Given numbers are 256, 768, 819, 216
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(256, 768) = 768
GCD(256, 768) = ( 256 x 768 ) / 768
= 256 / 768
= 256
Step2:
LCM(256, 819) = 209664
GCD(256, 819) = ( 256 x 819 ) / 209664
= 256 / 819
= 256
Step3:
LCM(1, 216) = 216
GCD(1, 216) = ( 1 x 216 ) / 216
= 1 / 216
= 1
So, Greatest Common Divisor of 256, 768, 819, 216 is 1
