Given numbers are 820, 294, 857

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

Apply this formula for all numbers.

Step1:

LCM(820, 294) = 120540

GCD(820, 294) = ( 820 x 294 ) / 120540

= 820 / 294

= 820

Step2:

LCM(2, 857) = 1714

GCD(2, 857) = ( 2 x 857 ) / 1714

= 2 / 857

= 2

So, Greatest Common Divisor of 820, 294, 857 is 1
