Given numbers are 196, 838, 821

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

Apply this formula for all numbers.

Step1:

LCM(196, 838) = 82124

GCD(196, 838) = ( 196 x 838 ) / 82124

= 196 / 838

= 196

Step2:

LCM(2, 821) = 1642

GCD(2, 821) = ( 2 x 821 ) / 1642

= 2 / 821

= 2

So, Greatest Common Divisor of 196, 838, 821 is 1
