Given numbers are 612, 646, 82, 381

The list of prime factors of all numbers are

Prime factors of 612 are 2 x 2 x 3 x 3 x 17

Prime factors of 646 are 2 x 17 x 19

Prime factors of 82 are 2 x 41

Prime factors of 381 are 3 x 127

Given numbers are 612, 646, 82, 381

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

Apply this formula for all numbers.

Step1:

LCM(612, 646) = 11628

GCD(612, 646) = ( 612 x 646 ) / 11628

= 612 / 646

= 612

Step2:

LCM(34, 82) = 1394

GCD(34, 82) = ( 34 x 82 ) / 1394

= 34 / 82

= 34

Step3:

LCM(2, 381) = 762

GCD(2, 381) = ( 2 x 381 ) / 762

= 2 / 381

= 2

So, Greatest Common Divisor of 612, 646, 82, 381 is 1
