Given numbers are 166, 285, 397, 203
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(166, 285) = 47310
GCD(166, 285) = ( 166 x 285 ) / 47310
= 166 / 285
= 166
Step2:
LCM(1, 397) = 397
GCD(1, 397) = ( 1 x 397 ) / 397
= 1 / 397
= 1
Step3:
LCM(1, 203) = 203
GCD(1, 203) = ( 1 x 203 ) / 203
= 1 / 203
= 1
So, Greatest Common Divisor of 166, 285, 397, 203 is 1
