Given numbers are 645, 196, 433, 834

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

Apply this formula for all numbers.

Step1:

LCM(645, 196) = 126420

GCD(645, 196) = ( 645 x 196 ) / 126420

= 645 / 196

= 645

Step2:

LCM(1, 433) = 433

GCD(1, 433) = ( 1 x 433 ) / 433

= 1 / 433

= 1

Step3:

LCM(1, 834) = 834

GCD(1, 834) = ( 1 x 834 ) / 834

= 1 / 834

= 1

So, Greatest Common Divisor of 645, 196, 433, 834 is 1
