Given numbers are 195, 686, 426, 122

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

Apply this formula for all numbers.

Step1:

LCM(195, 686) = 133770

GCD(195, 686) = ( 195 x 686 ) / 133770

= 195 / 686

= 195

Step2:

LCM(1, 426) = 426

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

= 1 / 426

= 1

Step3:

LCM(1, 122) = 122

GCD(1, 122) = ( 1 x 122 ) / 122

= 1 / 122

= 1

So, Greatest Common Divisor of 195, 686, 426, 122 is 1
