The list of prime factors of all numbers are

Prime factors of 969 are 3 x 17 x 19

Prime factors of 670 are 2 x 5 x 67

Prime factors of 828 are 2 x 2 x 3 x 3 x 23

Prime factors of 646 are 2 x 17 x 19

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

Given numbers are 969, 670, 828, 646

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

Apply this formula for all numbers.

Step1:

LCM(969, 670) = 649230

GCD(969, 670) = ( 969 x 670 ) / 649230

= 969 / 670

= 969

Step2:

LCM(1, 828) = 828

GCD(1, 828) = ( 1 x 828 ) / 828

= 1 / 828

= 1

Step3:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

So, Greatest Common Divisor of 969, 670, 828, 646 is 1
