Given numbers are 821, 711, 817, 166

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

Apply this formula for all numbers.

Step1:

LCM(821, 711) = 583731

GCD(821, 711) = ( 821 x 711 ) / 583731

= 821 / 711

= 821

Step2:

LCM(1, 817) = 817

GCD(1, 817) = ( 1 x 817 ) / 817

= 1 / 817

= 1

Step3:

LCM(1, 166) = 166

GCD(1, 166) = ( 1 x 166 ) / 166

= 1 / 166

= 1

So, Greatest Common Divisor of 821, 711, 817, 166 is 1
