Given numbers are 405, 124, 127, 808
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(405, 124) = 50220
GCD(405, 124) = ( 405 x 124 ) / 50220
= 405 / 124
= 405
Step2:
LCM(1, 127) = 127
GCD(1, 127) = ( 1 x 127 ) / 127
= 1 / 127
= 1
Step3:
LCM(1, 808) = 808
GCD(1, 808) = ( 1 x 808 ) / 808
= 1 / 808
= 1
So, Greatest Common Divisor of 405, 124, 127, 808 is 1
