Given numbers are 185, 998, 420, 459
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(185, 998) = 184630
GCD(185, 998) = ( 185 x 998 ) / 184630
= 185 / 998
= 185
Step2:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
Step3:
LCM(1, 459) = 459
GCD(1, 459) = ( 1 x 459 ) / 459
= 1 / 459
= 1
So, Greatest Common Divisor of 185, 998, 420, 459 is 1
