Given numbers are 436, 485, 784, 280

The list of prime factors of all numbers are

Prime factors of 436 are 2 x 2 x 109

Prime factors of 485 are 5 x 97

Prime factors of 784 are 2 x 2 x 2 x 2 x 7 x 7

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

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

Given numbers are 436, 485, 784, 280

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

Apply this formula for all numbers.

Step1:

LCM(436, 485) = 211460

GCD(436, 485) = ( 436 x 485 ) / 211460

= 436 / 485

= 436

Step2:

LCM(1, 784) = 784

GCD(1, 784) = ( 1 x 784 ) / 784

= 1 / 784

= 1

Step3:

LCM(1, 280) = 280

GCD(1, 280) = ( 1 x 280 ) / 280

= 1 / 280

= 1

So, Greatest Common Divisor of 436, 485, 784, 280 is 1
