Given numbers are 981, 109, 191, 408
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(981, 109) = 981
GCD(981, 109) = ( 981 x 109 ) / 981
= 981 / 109
= 981
Step2:
LCM(109, 191) = 20819
GCD(109, 191) = ( 109 x 191 ) / 20819
= 109 / 191
= 109
Step3:
LCM(1, 408) = 408
GCD(1, 408) = ( 1 x 408 ) / 408
= 1 / 408
= 1
So, Greatest Common Divisor of 981, 109, 191, 408 is 1
