Given numbers are 920, 475, 685, 803

The list of prime factors of all numbers are

Prime factors of 920 are 2 x 2 x 2 x 5 x 23

Prime factors of 475 are 5 x 5 x 19

Prime factors of 685 are 5 x 137

Prime factors of 803 are 11 x 73

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

Given numbers are 920, 475, 685, 803

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

Apply this formula for all numbers.

Step1:

LCM(920, 475) = 87400

GCD(920, 475) = ( 920 x 475 ) / 87400

= 920 / 475

= 920

Step2:

LCM(5, 685) = 685

GCD(5, 685) = ( 5 x 685 ) / 685

= 5 / 685

= 5

Step3:

LCM(5, 803) = 4015

GCD(5, 803) = ( 5 x 803 ) / 4015

= 5 / 803

= 5

So, Greatest Common Divisor of 920, 475, 685, 803 is 1
