Given numbers are 976, 441, 78, 855

The list of prime factors of all numbers are

Prime factors of 976 are 2 x 2 x 2 x 2 x 61

Prime factors of 441 are 3 x 3 x 7 x 7

Prime factors of 78 are 2 x 3 x 13

Prime factors of 855 are 3 x 3 x 5 x 19

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

Given numbers are 976, 441, 78, 855

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

Apply this formula for all numbers.

Step1:

LCM(976, 441) = 430416

GCD(976, 441) = ( 976 x 441 ) / 430416

= 976 / 441

= 976

Step2:

LCM(1, 78) = 78

GCD(1, 78) = ( 1 x 78 ) / 78

= 1 / 78

= 1

Step3:

LCM(1, 855) = 855

GCD(1, 855) = ( 1 x 855 ) / 855

= 1 / 855

= 1

So, Greatest Common Divisor of 976, 441, 78, 855 is 1
