Given numbers are 231, 689, 862, 166
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(231, 689) = 159159
GCD(231, 689) = ( 231 x 689 ) / 159159
= 231 / 689
= 231
Step2:
LCM(1, 862) = 862
GCD(1, 862) = ( 1 x 862 ) / 862
= 1 / 862
= 1
Step3:
LCM(1, 166) = 166
GCD(1, 166) = ( 1 x 166 ) / 166
= 1 / 166
= 1
So, Greatest Common Divisor of 231, 689, 862, 166 is 1
