Given numbers are 821, 231, 574

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

Apply this formula for all numbers.

Step1:

LCM(821, 231) = 189651

GCD(821, 231) = ( 821 x 231 ) / 189651

= 821 / 231

= 821

Step2:

LCM(1, 574) = 574

GCD(1, 574) = ( 1 x 574 ) / 574

= 1 / 574

= 1

So, Greatest Common Divisor of 821, 231, 574 is 1
