Given numbers are 309, 171, 43, 676
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(309, 171) = 17613
GCD(309, 171) = ( 309 x 171 ) / 17613
= 309 / 171
= 309
Step2:
LCM(3, 43) = 129
GCD(3, 43) = ( 3 x 43 ) / 129
= 3 / 43
= 3
Step3:
LCM(1, 676) = 676
GCD(1, 676) = ( 1 x 676 ) / 676
= 1 / 676
= 1
So, Greatest Common Divisor of 309, 171, 43, 676 is 1
