Given numbers are 247, 748, 820, 305

The list of prime factors of all numbers are

Prime factors of 247 are 13 x 19

Prime factors of 748 are 2 x 2 x 11 x 17

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

Prime factors of 305 are 5 x 61

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

Given numbers are 247, 748, 820, 305

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

Apply this formula for all numbers.

Step1:

LCM(247, 748) = 184756

GCD(247, 748) = ( 247 x 748 ) / 184756

= 247 / 748

= 247

Step2:

LCM(1, 820) = 820

GCD(1, 820) = ( 1 x 820 ) / 820

= 1 / 820

= 1

Step3:

LCM(1, 305) = 305

GCD(1, 305) = ( 1 x 305 ) / 305

= 1 / 305

= 1

So, Greatest Common Divisor of 247, 748, 820, 305 is 1
