Given numbers are 815, 196, 657

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

Apply this formula for all numbers.

Step1:

LCM(815, 196) = 159740

GCD(815, 196) = ( 815 x 196 ) / 159740

= 815 / 196

= 815

Step2:

LCM(1, 657) = 657

GCD(1, 657) = ( 1 x 657 ) / 657

= 1 / 657

= 1

So, Greatest Common Divisor of 815, 196, 657 is 1
