GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(445, 198) = 88110
GCD(445, 198) = ( 445 x 198 ) / 88110
= 445 / 198
= 445
Step2:
LCM(1, 978) = 978
GCD(1, 978) = ( 1 x 978 ) / 978
= 1 / 978
= 1
Step3:
LCM(1, 843) = 843
GCD(1, 843) = ( 1 x 843 ) / 843
= 1 / 843
= 1
