GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(287, 681) = 195447
GCD(287, 681) = ( 287 x 681 ) / 195447
= 287 / 681
= 287
Step2:
LCM(1, 856) = 856
GCD(1, 856) = ( 1 x 856 ) / 856
= 1 / 856
= 1
Step3:
LCM(1, 204) = 204
GCD(1, 204) = ( 1 x 204 ) / 204
= 1 / 204
= 1
So, Greatest Common Divisor of 287, 681, 856, 204 is 1
