Given numbers are 745, 990, 401, 869

The list of prime factors of all numbers are

Prime factors of 745 are 5 x 149

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

Prime factors of 401 are 401

Prime factors of 869 are 11 x 79

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

Given numbers are 745, 990, 401, 869

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

Apply this formula for all numbers.

Step1:

LCM(745, 990) = 147510

GCD(745, 990) = ( 745 x 990 ) / 147510

= 745 / 990

= 745

Step2:

LCM(5, 401) = 2005

GCD(5, 401) = ( 5 x 401 ) / 2005

= 5 / 401

= 5

Step3:

LCM(1, 869) = 869

GCD(1, 869) = ( 1 x 869 ) / 869

= 1 / 869

= 1

So, Greatest Common Divisor of 745, 990, 401, 869 is 1
