GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(219, 648) = 47304
GCD(219, 648) = ( 219 x 648 ) / 47304
= 219 / 648
= 219
Step2:
LCM(3, 213) = 213
GCD(3, 213) = ( 3 x 213 ) / 213
= 3 / 213
= 3
Step3:
LCM(3, 997) = 2991
GCD(3, 997) = ( 3 x 997 ) / 2991
= 3 / 997
= 3
So, Greatest Common Divisor of 219, 648, 213, 997 is 1
