GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(561, 384) = 71808
GCD(561, 384) = ( 561 x 384 ) / 71808
= 561 / 384
= 561
Step2:
LCM(3, 769) = 2307
GCD(3, 769) = ( 3 x 769 ) / 2307
= 3 / 769
= 3
Step3:
LCM(1, 171) = 171
GCD(1, 171) = ( 1 x 171 ) / 171
= 1 / 171
= 1
So, Greatest Common Divisor of 561, 384, 769, 171 is 1
