Given numbers are 231, 195, 346, 821
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(231, 195) = 15015
GCD(231, 195) = ( 231 x 195 ) / 15015
= 231 / 195
= 231
Step2:
LCM(3, 346) = 1038
GCD(3, 346) = ( 3 x 346 ) / 1038
= 3 / 346
= 3
Step3:
LCM(1, 821) = 821
GCD(1, 821) = ( 1 x 821 ) / 821
= 1 / 821
= 1
So, Greatest Common Divisor of 231, 195, 346, 821 is 1
