Given numbers are 408, 249, 981, 223
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(408, 249) = 33864
GCD(408, 249) = ( 408 x 249 ) / 33864
= 408 / 249
= 408
Step2:
LCM(3, 981) = 981
GCD(3, 981) = ( 3 x 981 ) / 981
= 3 / 981
= 3
Step3:
LCM(3, 223) = 669
GCD(3, 223) = ( 3 x 223 ) / 669
= 3 / 223
= 3
So, Greatest Common Divisor of 408, 249, 981, 223 is 1
