GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(978, 247) = 241566
GCD(978, 247) = ( 978 x 247 ) / 241566
= 978 / 247
= 978
Step2:
LCM(1, 729) = 729
GCD(1, 729) = ( 1 x 729 ) / 729
= 1 / 729
= 1
Step3:
LCM(1, 223) = 223
GCD(1, 223) = ( 1 x 223 ) / 223
= 1 / 223
= 1
So, Greatest Common Divisor of 978, 247, 729, 223 is 1
