Given numbers are 255, 987, 404, 287
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(255, 987) = 83895
GCD(255, 987) = ( 255 x 987 ) / 83895
= 255 / 987
= 255
Step2:
LCM(3, 404) = 1212
GCD(3, 404) = ( 3 x 404 ) / 1212
= 3 / 404
= 3
Step3:
LCM(1, 287) = 287
GCD(1, 287) = ( 1 x 287 ) / 287
= 1 / 287
= 1
So, Greatest Common Divisor of 255, 987, 404, 287 is 1
