Given numbers are 506, 645, 981, 193

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

Apply this formula for all numbers.

Step1:

LCM(506, 645) = 326370

GCD(506, 645) = ( 506 x 645 ) / 326370

= 506 / 645

= 506

Step2:

LCM(1, 981) = 981

GCD(1, 981) = ( 1 x 981 ) / 981

= 1 / 981

= 1

Step3:

LCM(1, 193) = 193

GCD(1, 193) = ( 1 x 193 ) / 193

= 1 / 193

= 1

So, Greatest Common Divisor of 506, 645, 981, 193 is 1
