Given numbers are 622, 978, 666, 509

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

Apply this formula for all numbers.

Step1:

LCM(622, 978) = 304158

GCD(622, 978) = ( 622 x 978 ) / 304158

= 622 / 978

= 622

Step2:

LCM(2, 666) = 666

GCD(2, 666) = ( 2 x 666 ) / 666

= 2 / 666

= 2

Step3:

LCM(2, 509) = 1018

GCD(2, 509) = ( 2 x 509 ) / 1018

= 2 / 509

= 2

So, Greatest Common Divisor of 622, 978, 666, 509 is 1
