GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(243, 720) = 19440
GCD(243, 720) = ( 243 x 720 ) / 19440
= 243 / 720
= 243
Step2:
LCM(9, 621) = 621
GCD(9, 621) = ( 9 x 621 ) / 621
= 9 / 621
= 9
Step3:
LCM(9, 419) = 3771
GCD(9, 419) = ( 9 x 419 ) / 3771
= 9 / 419
= 9
So, Greatest Common Divisor of 243, 720, 621, 419 is 1
