GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(236, 455) = 107380
GCD(236, 455) = ( 236 x 455 ) / 107380
= 236 / 455
= 236
Step2:
LCM(1, 808) = 808
GCD(1, 808) = ( 1 x 808 ) / 808
= 1 / 808
= 1
Step3:
LCM(1, 189) = 189
GCD(1, 189) = ( 1 x 189 ) / 189
= 1 / 189
= 1
So, Greatest Common Divisor of 236, 455, 808, 189 is 1
