Given numbers are 213, 721, 209, 629
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(213, 721) = 153573
GCD(213, 721) = ( 213 x 721 ) / 153573
= 213 / 721
= 213
Step2:
LCM(1, 209) = 209
GCD(1, 209) = ( 1 x 209 ) / 209
= 1 / 209
= 1
Step3:
LCM(1, 629) = 629
GCD(1, 629) = ( 1 x 629 ) / 629
= 1 / 629
= 1
So, Greatest Common Divisor of 213, 721, 209, 629 is 1
