GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(821, 683) = 560743
GCD(821, 683) = ( 821 x 683 ) / 560743
= 821 / 683
= 821
Step2:
LCM(1, 209) = 209
GCD(1, 209) = ( 1 x 209 ) / 209
= 1 / 209
= 1
Step3:
LCM(1, 103) = 103
GCD(1, 103) = ( 1 x 103 ) / 103
= 1 / 103
= 1
So, Greatest Common Divisor of 821, 683, 209, 103 is 1
