Given numbers are 195, 513, 491, 280

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

Apply this formula for all numbers.

Step1:

LCM(195, 513) = 33345

GCD(195, 513) = ( 195 x 513 ) / 33345

= 195 / 513

= 195

Step2:

LCM(3, 491) = 1473

GCD(3, 491) = ( 3 x 491 ) / 1473

= 3 / 491

= 3

Step3:

LCM(1, 280) = 280

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

= 1 / 280

= 1

So, Greatest Common Divisor of 195, 513, 491, 280 is 1
