Given numbers are 661, 801, 257, 199

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

Apply this formula for all numbers.

Step1:

LCM(661, 801) = 529461

GCD(661, 801) = ( 661 x 801 ) / 529461

= 661 / 801

= 661

Step2:

LCM(1, 257) = 257

GCD(1, 257) = ( 1 x 257 ) / 257

= 1 / 257

= 1

Step3:

LCM(1, 199) = 199

GCD(1, 199) = ( 1 x 199 ) / 199

= 1 / 199

= 1

So, Greatest Common Divisor of 661, 801, 257, 199 is 1
