Given numbers are 851, 280, 905, 437

The list of prime factors of all numbers are

Prime factors of 851 are 23 x 37

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

Prime factors of 905 are 5 x 181

Prime factors of 437 are 19 x 23

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

Given numbers are 851, 280, 905, 437

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

Apply this formula for all numbers.

Step1:

LCM(851, 280) = 238280

GCD(851, 280) = ( 851 x 280 ) / 238280

= 851 / 280

= 851

Step2:

LCM(1, 905) = 905

GCD(1, 905) = ( 1 x 905 ) / 905

= 1 / 905

= 1

Step3:

LCM(1, 437) = 437

GCD(1, 437) = ( 1 x 437 ) / 437

= 1 / 437

= 1

So, Greatest Common Divisor of 851, 280, 905, 437 is 1
