Given numbers are 197, 505, 781, 426

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

Apply this formula for all numbers.

Step1:

LCM(197, 505) = 99485

GCD(197, 505) = ( 197 x 505 ) / 99485

= 197 / 505

= 197

Step2:

LCM(1, 781) = 781

GCD(1, 781) = ( 1 x 781 ) / 781

= 1 / 781

= 1

Step3:

LCM(1, 426) = 426

GCD(1, 426) = ( 1 x 426 ) / 426

= 1 / 426

= 1

So, Greatest Common Divisor of 197, 505, 781, 426 is 1
