Given numbers are 269, 705, 820

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

Apply this formula for all numbers.

Step1:

LCM(269, 705) = 189645

GCD(269, 705) = ( 269 x 705 ) / 189645

= 269 / 705

= 269

Step2:

LCM(1, 820) = 820

GCD(1, 820) = ( 1 x 820 ) / 820

= 1 / 820

= 1

So, Greatest Common Divisor of 269, 705, 820 is 1
