Given numbers are 421, 565, 209, 915

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

Apply this formula for all numbers.

Step1:

LCM(421, 565) = 237865

GCD(421, 565) = ( 421 x 565 ) / 237865

= 421 / 565

= 421

Step2:

LCM(1, 209) = 209

GCD(1, 209) = ( 1 x 209 ) / 209

= 1 / 209

= 1

Step3:

LCM(1, 915) = 915

GCD(1, 915) = ( 1 x 915 ) / 915

= 1 / 915

= 1

So, Greatest Common Divisor of 421, 565, 209, 915 is 1
