Given numbers are 646, 308, 84, 755

The list of prime factors of all numbers are

Prime factors of 646 are 2 x 17 x 19

Prime factors of 308 are 2 x 2 x 7 x 11

Prime factors of 84 are 2 x 2 x 3 x 7

Prime factors of 755 are 5 x 151

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 646, 308, 84, 755

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

Apply this formula for all numbers.

Step1:

LCM(646, 308) = 99484

GCD(646, 308) = ( 646 x 308 ) / 99484

= 646 / 308

= 646

Step2:

LCM(2, 84) = 84

GCD(2, 84) = ( 2 x 84 ) / 84

= 2 / 84

= 2

Step3:

LCM(2, 755) = 1510

GCD(2, 755) = ( 2 x 755 ) / 1510

= 2 / 755

= 2

So, Greatest Common Divisor of 646, 308, 84, 755 is 1
