Given numbers are 305, 221, 255, 263
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(305, 221) = 67405
GCD(305, 221) = ( 305 x 221 ) / 67405
= 305 / 221
= 305
Step2:
LCM(1, 255) = 255
GCD(1, 255) = ( 1 x 255 ) / 255
= 1 / 255
= 1
Step3:
LCM(1, 263) = 263
GCD(1, 263) = ( 1 x 263 ) / 263
= 1 / 263
= 1
So, Greatest Common Divisor of 305, 221, 255, 263 is 1
