Given numbers are 978, 621, 397, 714

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

Apply this formula for all numbers.

Step1:

LCM(978, 621) = 202446

GCD(978, 621) = ( 978 x 621 ) / 202446

= 978 / 621

= 978

Step2:

LCM(3, 397) = 1191

GCD(3, 397) = ( 3 x 397 ) / 1191

= 3 / 397

= 3

Step3:

LCM(1, 714) = 714

GCD(1, 714) = ( 1 x 714 ) / 714

= 1 / 714

= 1

So, Greatest Common Divisor of 978, 621, 397, 714 is 1
