Given numbers are 646, 396, 33, 194

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

Apply this formula for all numbers.

Step1:

LCM(646, 396) = 127908

GCD(646, 396) = ( 646 x 396 ) / 127908

= 646 / 396

= 646

Step2:

LCM(2, 33) = 66

GCD(2, 33) = ( 2 x 33 ) / 66

= 2 / 33

= 2

Step3:

LCM(1, 194) = 194

GCD(1, 194) = ( 1 x 194 ) / 194

= 1 / 194

= 1

So, Greatest Common Divisor of 646, 396, 33, 194 is 1
