Given numbers are 309, 476, 265, 620

The list of prime factors of all numbers are

Prime factors of 309 are 3 x 103

Prime factors of 476 are 2 x 2 x 7 x 17

Prime factors of 265 are 5 x 53

Prime factors of 620 are 2 x 2 x 5 x 31

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

Given numbers are 309, 476, 265, 620

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

Apply this formula for all numbers.

Step1:

LCM(309, 476) = 147084

GCD(309, 476) = ( 309 x 476 ) / 147084

= 309 / 476

= 309

Step2:

LCM(1, 265) = 265

GCD(1, 265) = ( 1 x 265 ) / 265

= 1 / 265

= 1

Step3:

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

= 1 / 620

= 1

So, Greatest Common Divisor of 309, 476, 265, 620 is 1
