Given numbers are 196, 259, 161, 645

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

Apply this formula for all numbers.

Step1:

LCM(196, 259) = 7252

GCD(196, 259) = ( 196 x 259 ) / 7252

= 196 / 259

= 196

Step2:

LCM(7, 161) = 161

GCD(7, 161) = ( 7 x 161 ) / 161

= 7 / 161

= 7

Step3:

LCM(7, 645) = 4515

GCD(7, 645) = ( 7 x 645 ) / 4515

= 7 / 645

= 7

So, Greatest Common Divisor of 196, 259, 161, 645 is 1
