Given numbers are 287, 241, 20

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(287, 241) = 69167

GCD(287, 241) = ( 287 x 241 ) / 69167

= 287 / 241

= 287

Step2:

LCM(1, 20) = 20

GCD(1, 20) = ( 1 x 20 ) / 20

= 1 / 20

= 1

So, Greatest Common Divisor of 287, 241, 20 is 1
