Given numbers are 978, 248, 320, 419

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

Apply this formula for all numbers.

Step1:

LCM(978, 248) = 121272

GCD(978, 248) = ( 978 x 248 ) / 121272

= 978 / 248

= 978

Step2:

LCM(2, 320) = 320

GCD(2, 320) = ( 2 x 320 ) / 320

= 2 / 320

= 2

Step3:

LCM(2, 419) = 838

GCD(2, 419) = ( 2 x 419 ) / 838

= 2 / 419

= 2

So, Greatest Common Divisor of 978, 248, 320, 419 is 1
