GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(213, 981) = 69651
GCD(213, 981) = ( 213 x 981 ) / 69651
= 213 / 981
= 213
Step2:
LCM(3, 788) = 2364
GCD(3, 788) = ( 3 x 788 ) / 2364
= 3 / 788
= 3
Step3:
LCM(1, 623) = 623
GCD(1, 623) = ( 1 x 623 ) / 623
= 1 / 623
= 1
So, Greatest Common Divisor of 213, 981, 788, 623 is 1
