GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(287, 911) = 261457
GCD(287, 911) = ( 287 x 911 ) / 261457
= 287 / 911
= 287
Step2:
LCM(1, 311) = 311
GCD(1, 311) = ( 1 x 311 ) / 311
= 1 / 311
= 1
Step3:
LCM(1, 439) = 439
GCD(1, 439) = ( 1 x 439 ) / 439
= 1 / 439
= 1
So, Greatest Common Divisor of 287, 911, 311, 439 is 1
