Steps to Calculate GCD of 805, 197, 663, 866 using LCM Formula
Given numbers are 805, 197, 663, 866
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(805, 197) = 158585
GCD(805, 197) = ( 805 x 197 ) / 158585
= 805 / 197
= 805
Step2:
LCM(1, 663) = 663
GCD(1, 663) = ( 1 x 663 ) / 663
= 1 / 663
= 1
Step3:
LCM(1, 866) = 866
GCD(1, 866) = ( 1 x 866 ) / 866
= 1 / 866
= 1
So, Greatest Common Divisor of 805, 197, 663, 866 is 1
