Given numbers are 247, 475, 289, 286

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

Apply this formula for all numbers.

Step1:

LCM(247, 475) = 6175

GCD(247, 475) = ( 247 x 475 ) / 6175

= 247 / 475

= 247

Step2:

LCM(19, 289) = 5491

GCD(19, 289) = ( 19 x 289 ) / 5491

= 19 / 289

= 19

Step3:

LCM(1, 286) = 286

GCD(1, 286) = ( 1 x 286 ) / 286

= 1 / 286

= 1

So, Greatest Common Divisor of 247, 475, 289, 286 is 1
