Given numbers are 978, 509, 603, 625

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

Apply this formula for all numbers.

Step1:

LCM(978, 509) = 497802

GCD(978, 509) = ( 978 x 509 ) / 497802

= 978 / 509

= 978

Step2:

LCM(1, 603) = 603

GCD(1, 603) = ( 1 x 603 ) / 603

= 1 / 603

= 1

Step3:

LCM(1, 625) = 625

GCD(1, 625) = ( 1 x 625 ) / 625

= 1 / 625

= 1

So, Greatest Common Divisor of 978, 509, 603, 625 is 1
