Given numbers are 851, 420, 415, 755

The list of prime factors of all numbers are

Prime factors of 851 are 23 x 37

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 415 are 5 x 83

Prime factors of 755 are 5 x 151

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

Given numbers are 851, 420, 415, 755

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

Apply this formula for all numbers.

Step1:

LCM(851, 420) = 357420

GCD(851, 420) = ( 851 x 420 ) / 357420

= 851 / 420

= 851

Step2:

LCM(1, 415) = 415

GCD(1, 415) = ( 1 x 415 ) / 415

= 1 / 415

= 1

Step3:

LCM(1, 755) = 755

GCD(1, 755) = ( 1 x 755 ) / 755

= 1 / 755

= 1

So, Greatest Common Divisor of 851, 420, 415, 755 is 1
