Given numbers are 821, 192, 670

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

Apply this formula for all numbers.

Step1:

LCM(821, 192) = 157632

GCD(821, 192) = ( 821 x 192 ) / 157632

= 821 / 192

= 821

Step2:

LCM(1, 670) = 670

GCD(1, 670) = ( 1 x 670 ) / 670

= 1 / 670

= 1

So, Greatest Common Divisor of 821, 192, 670 is 1
