Given numbers are 213, 309, 471, 853
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(213, 309) = 21939
GCD(213, 309) = ( 213 x 309 ) / 21939
= 213 / 309
= 213
Step2:
LCM(3, 471) = 471
GCD(3, 471) = ( 3 x 471 ) / 471
= 3 / 471
= 3
Step3:
LCM(3, 853) = 2559
GCD(3, 853) = ( 3 x 853 ) / 2559
= 3 / 853
= 3
So, Greatest Common Divisor of 213, 309, 471, 853 is 1
