GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(549, 436) = 239364
GCD(549, 436) = ( 549 x 436 ) / 239364
= 549 / 436
= 549
Step2:
LCM(1, 843) = 843
GCD(1, 843) = ( 1 x 843 ) / 843
= 1 / 843
= 1
Step3:
LCM(1, 189) = 189
GCD(1, 189) = ( 1 x 189 ) / 189
= 1 / 189
= 1
So, Greatest Common Divisor of 549, 436, 843, 189 is 1
