Given numbers are 692, 247, 477, 780

The list of prime factors of all numbers are

Prime factors of 692 are 2 x 2 x 173

Prime factors of 247 are 13 x 19

Prime factors of 477 are 3 x 3 x 53

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

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

Given numbers are 692, 247, 477, 780

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

Apply this formula for all numbers.

Step1:

LCM(692, 247) = 170924

GCD(692, 247) = ( 692 x 247 ) / 170924

= 692 / 247

= 692

Step2:

LCM(1, 477) = 477

GCD(1, 477) = ( 1 x 477 ) / 477

= 1 / 477

= 1

Step3:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

So, Greatest Common Divisor of 692, 247, 477, 780 is 1
