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

Apply this formula for all numbers.

Step1:

LCM(621, 574) = 356454

GCD(621, 574) = ( 621 x 574 ) / 356454

= 621 / 574

= 621

Step2:

LCM(1, 978) = 978

GCD(1, 978) = ( 1 x 978 ) / 978

= 1 / 978

= 1

Step3:

LCM(1, 325) = 325

GCD(1, 325) = ( 1 x 325 ) / 325

= 1 / 325

= 1

So, Greatest Common Divisor of 621, 574, 978, 325 is 1
