Given numbers are 823, 451, 420, 269
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(823, 451) = 371173
GCD(823, 451) = ( 823 x 451 ) / 371173
= 823 / 451
= 823
Step2:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
Step3:
LCM(1, 269) = 269
GCD(1, 269) = ( 1 x 269 ) / 269
= 1 / 269
= 1
So, Greatest Common Divisor of 823, 451, 420, 269 is 1
