Given numbers are 861, 662, 305, 579

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

Apply this formula for all numbers.

Step1:

LCM(861, 662) = 569982

GCD(861, 662) = ( 861 x 662 ) / 569982

= 861 / 662

= 861

Step2:

LCM(1, 305) = 305

GCD(1, 305) = ( 1 x 305 ) / 305

= 1 / 305

= 1

Step3:

LCM(1, 579) = 579

GCD(1, 579) = ( 1 x 579 ) / 579

= 1 / 579

= 1

So, Greatest Common Divisor of 861, 662, 305, 579 is 1
