Given numbers are 211, 122, 470, 861
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(211, 122) = 25742
GCD(211, 122) = ( 211 x 122 ) / 25742
= 211 / 122
= 211
Step2:
LCM(1, 470) = 470
GCD(1, 470) = ( 1 x 470 ) / 470
= 1 / 470
= 1
Step3:
LCM(1, 861) = 861
GCD(1, 861) = ( 1 x 861 ) / 861
= 1 / 861
= 1
So, Greatest Common Divisor of 211, 122, 470, 861 is 1
