Given numbers are 409, 615, 234, 247

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

Apply this formula for all numbers.

Step1:

LCM(409, 615) = 251535

GCD(409, 615) = ( 409 x 615 ) / 251535

= 409 / 615

= 409

Step2:

LCM(1, 234) = 234

GCD(1, 234) = ( 1 x 234 ) / 234

= 1 / 234

= 1

Step3:

LCM(1, 247) = 247

GCD(1, 247) = ( 1 x 247 ) / 247

= 1 / 247

= 1

So, Greatest Common Divisor of 409, 615, 234, 247 is 1
