Given numbers are 409, 836, 574, 405
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(409, 836) = 341924
GCD(409, 836) = ( 409 x 836 ) / 341924
= 409 / 836
= 409
Step2:
LCM(1, 574) = 574
GCD(1, 574) = ( 1 x 574 ) / 574
= 1 / 574
= 1
Step3:
LCM(1, 405) = 405
GCD(1, 405) = ( 1 x 405 ) / 405
= 1 / 405
= 1
So, Greatest Common Divisor of 409, 836, 574, 405 is 1
