Given numbers are 280, 160, 747, 385

The list of prime factors of all numbers are

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

Prime factors of 160 are 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 747 are 3 x 3 x 83

Prime factors of 385 are 5 x 7 x 11

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

Given numbers are 280, 160, 747, 385

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

Apply this formula for all numbers.

Step1:

LCM(280, 160) = 1120

GCD(280, 160) = ( 280 x 160 ) / 1120

= 280 / 160

= 280

Step2:

LCM(40, 747) = 29880

GCD(40, 747) = ( 40 x 747 ) / 29880

= 40 / 747

= 40

Step3:

LCM(1, 385) = 385

GCD(1, 385) = ( 1 x 385 ) / 385

= 1 / 385

= 1

So, Greatest Common Divisor of 280, 160, 747, 385 is 1
