Given numbers are 808, 124, 280, 247

The list of prime factors of all numbers are

Prime factors of 808 are 2 x 2 x 2 x 101

Prime factors of 124 are 2 x 2 x 31

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 247 are 13 x 19

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

Given numbers are 808, 124, 280, 247

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

Apply this formula for all numbers.

Step1:

LCM(808, 124) = 25048

GCD(808, 124) = ( 808 x 124 ) / 25048

= 808 / 124

= 808

Step2:

LCM(4, 280) = 280

GCD(4, 280) = ( 4 x 280 ) / 280

= 4 / 280

= 4

Step3:

LCM(4, 247) = 988

GCD(4, 247) = ( 4 x 247 ) / 988

= 4 / 247

= 4

So, Greatest Common Divisor of 808, 124, 280, 247 is 1
