Given numbers are 861, 697, 705, 491

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

Apply this formula for all numbers.

Step1:

LCM(861, 697) = 14637

GCD(861, 697) = ( 861 x 697 ) / 14637

= 861 / 697

= 861

Step2:

LCM(41, 705) = 28905

GCD(41, 705) = ( 41 x 705 ) / 28905

= 41 / 705

= 41

Step3:

LCM(1, 491) = 491

GCD(1, 491) = ( 1 x 491 ) / 491

= 1 / 491

= 1

So, Greatest Common Divisor of 861, 697, 705, 491 is 1
