Given numbers are 981, 183, 243, 997
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(981, 183) = 59841
GCD(981, 183) = ( 981 x 183 ) / 59841
= 981 / 183
= 981
Step2:
LCM(3, 243) = 243
GCD(3, 243) = ( 3 x 243 ) / 243
= 3 / 243
= 3
Step3:
LCM(3, 997) = 2991
GCD(3, 997) = ( 3 x 997 ) / 2991
= 3 / 997
= 3
So, Greatest Common Divisor of 981, 183, 243, 997 is 1
