Given numbers are 661, 857, 194, 306

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

Apply this formula for all numbers.

Step1:

LCM(661, 857) = 566477

GCD(661, 857) = ( 661 x 857 ) / 566477

= 661 / 857

= 661

Step2:

LCM(1, 194) = 194

GCD(1, 194) = ( 1 x 194 ) / 194

= 1 / 194

= 1

Step3:

LCM(1, 306) = 306

GCD(1, 306) = ( 1 x 306 ) / 306

= 1 / 306

= 1

So, Greatest Common Divisor of 661, 857, 194, 306 is 1
