Given numbers are 969, 978, 808, 540

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

Apply this formula for all numbers.

Step1:

LCM(969, 978) = 315894

GCD(969, 978) = ( 969 x 978 ) / 315894

= 969 / 978

= 969

Step2:

LCM(3, 808) = 2424

GCD(3, 808) = ( 3 x 808 ) / 2424

= 3 / 808

= 3

Step3:

LCM(1, 540) = 540

GCD(1, 540) = ( 1 x 540 ) / 540

= 1 / 540

= 1

So, Greatest Common Divisor of 969, 978, 808, 540 is 1
