Given numbers are 665, 978, 568, 512

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

Apply this formula for all numbers.

Step1:

LCM(665, 978) = 650370

GCD(665, 978) = ( 665 x 978 ) / 650370

= 665 / 978

= 665

Step2:

LCM(1, 568) = 568

GCD(1, 568) = ( 1 x 568 ) / 568

= 1 / 568

= 1

Step3:

LCM(1, 512) = 512

GCD(1, 512) = ( 1 x 512 ) / 512

= 1 / 512

= 1

So, Greatest Common Divisor of 665, 978, 568, 512 is 1
