Given numbers are 815, 805, 278, 832

The list of prime factors of all numbers are

Prime factors of 815 are 5 x 163

Prime factors of 805 are 5 x 7 x 23

Prime factors of 278 are 2 x 139

Prime factors of 832 are 2 x 2 x 2 x 2 x 2 x 2 x 13

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

Given numbers are 815, 805, 278, 832

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

Apply this formula for all numbers.

Step1:

LCM(815, 805) = 131215

GCD(815, 805) = ( 815 x 805 ) / 131215

= 815 / 805

= 815

Step2:

LCM(5, 278) = 1390

GCD(5, 278) = ( 5 x 278 ) / 1390

= 5 / 278

= 5

Step3:

LCM(1, 832) = 832

GCD(1, 832) = ( 1 x 832 ) / 832

= 1 / 832

= 1

So, Greatest Common Divisor of 815, 805, 278, 832 is 1
