GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(775, 243) = 188325
GCD(775, 243) = ( 775 x 243 ) / 188325
= 775 / 243
= 775
Step2:
LCM(1, 816) = 816
GCD(1, 816) = ( 1 x 816 ) / 816
= 1 / 816
= 1
Step3:
LCM(1, 198) = 198
GCD(1, 198) = ( 1 x 198 ) / 198
= 1 / 198
= 1
So, Greatest Common Divisor of 775, 243, 816, 198 is 1
