Given numbers are 564, 309, 861, 862

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

Apply this formula for all numbers.

Step1:

LCM(564, 309) = 58092

GCD(564, 309) = ( 564 x 309 ) / 58092

= 564 / 309

= 564

Step2:

LCM(3, 861) = 861

GCD(3, 861) = ( 3 x 861 ) / 861

= 3 / 861

= 3

Step3:

LCM(3, 862) = 2586

GCD(3, 862) = ( 3 x 862 ) / 2586

= 3 / 862

= 3

So, Greatest Common Divisor of 564, 309, 861, 862 is 1
