Given numbers are 622, 481, 978, 815

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

Apply this formula for all numbers.

Step1:

LCM(622, 481) = 299182

GCD(622, 481) = ( 622 x 481 ) / 299182

= 622 / 481

= 622

Step2:

LCM(1, 978) = 978

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

= 1 / 978

= 1

Step3:

LCM(1, 815) = 815

GCD(1, 815) = ( 1 x 815 ) / 815

= 1 / 815

= 1

So, Greatest Common Divisor of 622, 481, 978, 815 is 1
