Given numbers are 577, 565, 815, 978

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

Apply this formula for all numbers.

Step1:

LCM(577, 565) = 326005

GCD(577, 565) = ( 577 x 565 ) / 326005

= 577 / 565

= 577

Step2:

LCM(1, 815) = 815

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

= 1 / 815

= 1

Step3:

LCM(1, 978) = 978

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

= 1 / 978

= 1

So, Greatest Common Divisor of 577, 565, 815, 978 is 1
