Given numbers are 690, 399, 477, 247

The list of prime factors of all numbers are

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 399 are 3 x 7 x 19

Prime factors of 477 are 3 x 3 x 53

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 690, 399, 477, 247

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

Apply this formula for all numbers.

Step1:

LCM(690, 399) = 91770

GCD(690, 399) = ( 690 x 399 ) / 91770

= 690 / 399

= 690

Step2:

LCM(3, 477) = 477

GCD(3, 477) = ( 3 x 477 ) / 477

= 3 / 477

= 3

Step3:

LCM(3, 247) = 741

GCD(3, 247) = ( 3 x 247 ) / 741

= 3 / 247

= 3

So, Greatest Common Divisor of 690, 399, 477, 247 is 1
