Given numbers are 978, 494, 288, 247

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

Apply this formula for all numbers.

Step1:

LCM(978, 494) = 241566

GCD(978, 494) = ( 978 x 494 ) / 241566

= 978 / 494

= 978

Step2:

LCM(2, 288) = 288

GCD(2, 288) = ( 2 x 288 ) / 288

= 2 / 288

= 2

Step3:

LCM(2, 247) = 494

GCD(2, 247) = ( 2 x 247 ) / 494

= 2 / 247

= 2

So, Greatest Common Divisor of 978, 494, 288, 247 is 1
