Given numbers are 621, 820, 266, 969

The list of prime factors of all numbers are

Prime factors of 621 are 3 x 3 x 3 x 23

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 266 are 2 x 7 x 19

Prime factors of 969 are 3 x 17 x 19

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

Given numbers are 621, 820, 266, 969

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

Apply this formula for all numbers.

Step1:

LCM(621, 820) = 509220

GCD(621, 820) = ( 621 x 820 ) / 509220

= 621 / 820

= 621

Step2:

LCM(1, 266) = 266

GCD(1, 266) = ( 1 x 266 ) / 266

= 1 / 266

= 1

Step3:

LCM(1, 969) = 969

GCD(1, 969) = ( 1 x 969 ) / 969

= 1 / 969

= 1

So, Greatest Common Divisor of 621, 820, 266, 969 is 1
