Given numbers are 861, 705, 783, 266

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

Apply this formula for all numbers.

Step1:

LCM(861, 705) = 202335

GCD(861, 705) = ( 861 x 705 ) / 202335

= 861 / 705

= 861

Step2:

LCM(3, 783) = 783

GCD(3, 783) = ( 3 x 783 ) / 783

= 3 / 783

= 3

Step3:

LCM(3, 266) = 798

GCD(3, 266) = ( 3 x 266 ) / 798

= 3 / 266

= 3

So, Greatest Common Divisor of 861, 705, 783, 266 is 1
