Given numbers are 285, 615, 403, 591
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(285, 615) = 11685
GCD(285, 615) = ( 285 x 615 ) / 11685
= 285 / 615
= 285
Step2:
LCM(15, 403) = 6045
GCD(15, 403) = ( 15 x 403 ) / 6045
= 15 / 403
= 15
Step3:
LCM(1, 591) = 591
GCD(1, 591) = ( 1 x 591 ) / 591
= 1 / 591
= 1
So, Greatest Common Divisor of 285, 615, 403, 591 is 1
