GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(987, 897) = 295113
GCD(987, 897) = ( 987 x 897 ) / 295113
= 987 / 897
= 987
Step2:
LCM(3, 237) = 237
GCD(3, 237) = ( 3 x 237 ) / 237
= 3 / 237
= 3
Step3:
LCM(3, 249) = 249
GCD(3, 249) = ( 3 x 249 ) / 249
= 3 / 249
= 3
So, Greatest Common Divisor of 987, 897, 237, 249 is 3
