Given numbers are 411, 646, 823, 436
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(411, 646) = 265506
GCD(411, 646) = ( 411 x 646 ) / 265506
= 411 / 646
= 411
Step2:
LCM(1, 823) = 823
GCD(1, 823) = ( 1 x 823 ) / 823
= 1 / 823
= 1
Step3:
LCM(1, 436) = 436
GCD(1, 436) = ( 1 x 436 ) / 436
= 1 / 436
= 1
So, Greatest Common Divisor of 411, 646, 823, 436 is 1
