GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(243, 195) = 15795
GCD(243, 195) = ( 243 x 195 ) / 15795
= 243 / 195
= 243
Step2:
LCM(3, 985) = 2955
GCD(3, 985) = ( 3 x 985 ) / 2955
= 3 / 985
= 3
Step3:
LCM(1, 806) = 806
GCD(1, 806) = ( 1 x 806 ) / 806
= 1 / 806
= 1
So, Greatest Common Divisor of 243, 195, 985, 806 is 1
