Given numbers are 287, 306, 328, 485
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(287, 306) = 87822
GCD(287, 306) = ( 287 x 306 ) / 87822
= 287 / 306
= 287
Step2:
LCM(1, 328) = 328
GCD(1, 328) = ( 1 x 328 ) / 328
= 1 / 328
= 1
Step3:
LCM(1, 485) = 485
GCD(1, 485) = ( 1 x 485 ) / 485
= 1 / 485
= 1
So, Greatest Common Divisor of 287, 306, 328, 485 is 1
