GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(321, 412) = 132252
GCD(321, 412) = ( 321 x 412 ) / 132252
= 321 / 412
= 321
Step2:
LCM(1, 618) = 618
GCD(1, 618) = ( 1 x 618 ) / 618
= 1 / 618
= 1
Step3:
LCM(1, 819) = 819
GCD(1, 819) = ( 1 x 819 ) / 819
= 1 / 819
= 1
So, Greatest Common Divisor of 321, 412, 618, 819 is 1
