Given numbers are 193, 641, 280, 351

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

Apply this formula for all numbers.

Step1:

LCM(193, 641) = 123713

GCD(193, 641) = ( 193 x 641 ) / 123713

= 193 / 641

= 193

Step2:

LCM(1, 280) = 280

GCD(1, 280) = ( 1 x 280 ) / 280

= 1 / 280

= 1

Step3:

LCM(1, 351) = 351

GCD(1, 351) = ( 1 x 351 ) / 351

= 1 / 351

= 1

So, Greatest Common Divisor of 193, 641, 280, 351 is 1
