Prime factors of 392 are 2 x 2 x 2 x 7 x 7

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

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

Given numbers are 860, 969, 392, 520

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

Apply this formula for all numbers.

Step1:

LCM(860, 969) = 833340

GCD(860, 969) = ( 860 x 969 ) / 833340

= 860 / 969

= 860

Step2:

LCM(1, 392) = 392

GCD(1, 392) = ( 1 x 392 ) / 392

= 1 / 392

= 1

Step3:

LCM(1, 520) = 520

GCD(1, 520) = ( 1 x 520 ) / 520

= 1 / 520

= 1

So, Greatest Common Divisor of 860, 969, 392, 520 is 1
