Given numbers are 221, 105, 298, 486

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

Apply this formula for all numbers.

Step1:

LCM(221, 105) = 23205

GCD(221, 105) = ( 221 x 105 ) / 23205

= 221 / 105

= 221

Step2:

LCM(1, 298) = 298

GCD(1, 298) = ( 1 x 298 ) / 298

= 1 / 298

= 1

Step3:

LCM(1, 486) = 486

GCD(1, 486) = ( 1 x 486 ) / 486

= 1 / 486

= 1

So, Greatest Common Divisor of 221, 105, 298, 486 is 1
